Automatic piston ring inspections!

PSA carries out automatic piston ring inspections using Keyence laser displacement sensors. These accurate measurements have been made continuously and successfully for several years.
The Trémery factory, set up in 1979, is located 20 kilometres from Metz and has a staff of 3,740. It specialises in assembly of 4-cylinder diesel engines and has a daily production of 6,500 units, which makes it the biggest diesel engine assembly factory in the world, and the fourth largest taking all power sources together. 

The piston rings are fitted by a robot. The rings feature a gap and when they are expanded, they slide into grooves which have been created into the piston to house them. The pistons are critical components whose main purpose is to prevent combustion gases from escaping into the engine crankcase, so as to avoid loss of gas pressure and engine power. They also help to keep the engine´s lubricating oil out of the combustion chamber, while leaving a lubricating film of a predetermined thickness over the full surface area of the cylinder walls. Correct fitting of these moving sealing parts is essential to keep the engine running efficiently.

Pistons are fitted with 3 rings: the scraper ring, which is the most critical in regards to inspection because it is very thin and has a small spring that breaks easily, the compression ring, and lastly the top or "fire" ring that is 3 mm high and is the easiest to inspect. The piston rings are checked automatically at the Trémery PSA factory. A robot places the piston on a turntable, and four sensors are located on each side of the piston, opposite the first two rings. Each sensor inspects half of a ring. An initial rotation through 180° is made to check the first two rings with the 4 sensors. The turntable then rises along the Z axis. A second rotation is made in the opposite direction to inspect the third ring, using 2 sensors. If a ring is found to be nonconforming, it is inspected again, and then a third time. If the defect is confirmed, the piston is sent to an operator for further analysis.

"The displacement sensors measure all the dimensions of each of the half-perimeters that they are analysing. About 2,500 measurements are made per full turn, giving a pitch of less than one tenth of a millimetre. An inspection cycle of the 3 rings takes about 5 seconds.
¨We have determined thresholds to check the presence and the position of the 3 rings in the middle of the groove, together with the size and position of the gap. We also check the spring on the scraper ring via its gaps. To do so, we have selected the Keyence LK-G32 high-precision model with a small, 30-micron spot, as otherwise the spot was too big to enter the gaps", explains Claude Tritz, an assembly maintenance technician at the Trémery PSA factory.
Two LK-G models are used: 2 heads with small spots 30 microns in diameter (LK-G32) to inspect the scraper and compression rings, and 2 LK-G82 heads to detect the top ring.
The LKG sensors are laser displacement sensors. They provide a sampling speed of 50 kHz with a repeatability level of 0.05 µm for the most accurate models. Piston rings are reflective parts, and this affects the measurements. The LK-G range enables stable detection of transparent plastic and metal objects, thanks to its correction functions. The ABLE (Active Balanced Laser control Engine) technology detects the surface of a target and adjusts the laser light intensity to the optimum level. ABLE intelligently controls three parameters: laser emission time, laser power level, and gain (CCD amplification factor), thus providing a wide range of light intensity adjustment that is up to 90 times greater than that of conventional models. The MRC (Multiple Reflection Cancel) algorithm enables elimination of multiple reflections from a metal surface. When at least two peaks are generated by multiple reflections, the algorithm compares the wave forms with the last light wave form received and determines which one shows the greatest similarity with the "correct wave form".

"We have been using this solution for years now; in comparison to the previous solution, we have considerably reduced the numbers of false defects. It is to be noted that 3,000 engines are assembled on a continuous basis every day on the lines inspected by the LK-G sensors, in a very difficult environment. Nonetheless, the LK-G sensors stand up to the conditions very well", concludes Claude Tritz.

Force measurement using piezoelectric sensors

In November, Kistler Instruments will be holding two one day seminars to provide an introduction to piezoelectric sensor technology for instrumentation engineers. The seminars will cover the theory of piezoelectric sensors and the practical application of piezoelectric measurement in both laboratory and industrial environments.

The seminars will be relevant to all those responsible for designing and building instrumentation and measurement systems, especially where challenging environmental conditions may be encountered. A major quality of piezoelectric sensors is the ability to monitor highly dynamic impact events, often under harsh operating conditions.

Although piezoelectric sensor technology has many advantages over other types of sensor technologies, a clear understanding of piezoelectric measurement is essential for the full benefits to be obtained under real world conditions.

R&D 100 Award for high power SMU instrument!

The Model 2657A High Power System SourceMeter® Source Measure Unit (SMU) Instrument from Keithley has received the R&D 100 Award from R&D (Research & Development) magazine. This R&D 100 Award recognizes the Model 2657A, which was introduced in 2012, as one of the year's 100 most significant technology innovations worldwide and marks the 23rd time that Keithley has been honoured with this distinction by the editors of R&D magazine. Representatives from the Model 2657A Development Team will accept the award on behalf of Keithley during ceremonies to be held November 7 at the Renaissance Orlando Hotel (FL USA).

High voltage electronics, materials, and power semiconductor end applications are becoming increasingly demanding, requiring test instrumentation capable of characterizing devices with
significantly higher breakdown voltages and lower leakage currents and higher power levels than ever before. The Model 2657A, which allows researchers and engineers to make electrical measurements at up to 3,000 volts while measuring down to 1fA, is part of Keithley's growing line of precision sourcing and measurement instruments. The Model 2657A can source up to five times as much power to test a device as the nearest competitive solution, at significantly lower cost.

The Model 2657A is the highest voltage instrument a Keithley development team has ever designed. Its combination of requirements necessitated re-evaluating all Keithley safety practices and demanded exceptional discipline and ingenuity in terms of design.

Lee Stauffer, the senior staff technologist who led the Model 2657A Development Team, noted, "It's gratifying that the editors at R&D recognized the advantages the Model 2657A offers. Its
combination of high voltage at high power levels and ultra-low current resolution lets researchers and engineers capture important data that other solutions can't."

Siemens at the drinktec!

Not all beers are alike
– for a beer sommelier hops and malt are the ultimate clues

The event that will be the prelude to this year‘s drinktec, the world‘s leading trade fair for the beverage and liquid food industry, is to be held on 15 September: the Beer Sommelier World Championship. This championship, held every two years, highlights not only the vast range of beers available and the sommeliers familiar with them but also the breweries. Siemens supports the championship in its capacity as a technology partner of and vendor of automation technology to breweries worldwide. Siemens will be showcasing its extensive portfolio of integrated automation and drive solutions for breweries and beverage producers at drinktec, due to open on 16 September 2013.

More and more beer enthusiasts are opting to undergo the two-week training required to qualify as a beer sommelier. All the courses scheduled for 2014 are already fully booked. A beer sommelier learns how to distinguish up to 100 different beer types on the basis of taste and aroma. The world‘s best beer sommelier is selected every two years. The next Beer Sommelier World Championship will be held on 15 September 2013 in Munich. This year, competitors from 11 countries will eagerly await the final announcement of a jury composed of acknowledged experts.

There are over 5,000 beer varieties in Germany alone. Whereas in Germany the ingredients of beer are restricted to hops, malt, yeast and water only, other countries have been free to develop a gigantic range of beer types and formulae – from honey beer in Belgium to nougat beer in France. The sheer diversity of the beer world and constant new trends make the work of today‘s beer sommelier increasingly challenging. Just as a wine sommelier can judge the quality of a wine, a beer sommelier is qualified to assess the quality of a beer. A beer sommelier can advise restaurant patrons which beer is best suited to a given dish and can compile appropriate beer lists for restaurant owners. But more importantly he is responsible within the restaurant for the presentation and the quality of the beer as served. The current world champion is Sebastian B. Priller-Riegele. Just as the future world champion will be required to do, Sebastian Priller-Riegele had to outperform his co-competitors in beer tastings by detecting certain flavours or off-flavours in a range of beer samples. In the final phase of the championship, six finalists are required to savour and then classify a beer that is unfamiliar to them. The challenge here is to identify the sometimes many different hop varieties used in that beer‘s formula. The Doemens Academy, an internationally operating training and consultancy enterprise for the brewing industry, offers training courses leading to qualification as a beer sommelier.
The international brewing and beverage industry meets at the drinktec in Munich (D) every four years. The next drinktec, acknowledged as the leading platform for the industry worldwide, will be held from 16 to 20 September. Siemens Industry, a longstanding engineering partner of breweries and beverage producers all over the world, will again be showcasing its products at its own booth.

The engineering group will be presenting its comprehensive portfolio of integrated automation and drive solutions in Hall A4, Booth 107. At this year’s fair, Siemens’ main focus will include its DFT(Dairy Functional Toolset) software which complements the Simatic PCS 7 process control system with special functions for the dairy industry. By enabling dairies to precisely control specific workflows such as milk sampling, pasteurization, separation, production, and the cleaning of pipes and tanks, DFT is a tool for optimizing production processes throughout the industry. Moreover, DFT continuously collects and archives the production data. Other key exhibits include the OPL(Optimized Packaging Line) for bottling and packaging lines and solutions for optimizing energy management and energy-saving in beverage production. Visitors will also have an opportunity to find out more about the tried and tested Braumat.

Oils & Fat
In parallel of drinktec, the oils+fats will be taking place from 18 to 20 September 2013. oils + fats is the world’s only trade fair focusing on the technology and trading of oils and fats. For the fifth time in a row, this international edible oils and fats fair will be held in Munich (D). Siemens Industry, a provider of solutions for the edible oil industry, will be present in Hall B0, Booth 312, where it will showcase its Advanced Process Control(APC), Condition Monitoring by means of smart process data management, energy saving options using energy data monitoring, the innovative level gauge system for bulk silos featuring Sitrans LR 560 in 78GHz technology and the Simatic PCS 7 process control system with integrated functional safety features compliant with ISO 51611.

Putting a test case for integrity management!

Widely-publicised catastrophic failures of forged materials in deepwater applications have called into question the structural integrity of such products and focused industry attention on the need for carefully-managed ‘integrity management’ of key components. Errors in material selection at the design stage, the use of incorrect heat treatment techniques and inconsistent mechanical testing regimes, often involving test pieces not taken from the actual components, can lead to product failures during operation, typically resulting in significant environmental, safety and financial costs.

With suppliers to the oil & gas and marine industries particularly appreciating the need for integrity management of deep sea components to prevent expensive failures or prolonged shutdowns, Keighley Laboratories is experiencing an upturn in demand for first article inspection of pre-production components, to ensure meeting operators’ engineering specifications. It is a preventative measure that the company believes could be adopted more widely, especially with the life expectancy of products extending from ten years to 25 years or more, often in extremely harsh and corrosive environments.

“Product failures bring problems that engineering companies simply don’t need, wasting time, money and damaging their commercial reputations, when customers are inconvenienced,” says Leonard Stott, Customer Support Manager for Keighley Labs’ Technical Services division. “More than ever there is a definite requirement for proven product reliability and fitness-for-purpose, as well as a need for consistent mechanical and corrosion properties that can only be achieved by applying the correct processing and heat treatment techniques. Also, product testing procedures need to be accurate, not least the correct positioning and orientation of test sample pieces, to ensure optimum and consistent test values.
“It would be costly for suppliers to set up the necessary in-house procedures to ensure critical mistakes don’t happen, so it is worthwhile sub-contracting the metallurgical testing of components to independent experts like ourselves. We are specialists in the analysis, testing and heat treatment of metals, holding many leading quality accreditations relevant to various industry sectors, and we have the in-depth metallurgical knowledge and experience for the assessment of potential failures and the development of risk mitigation strategies.”

It was the catastrophic failure of a mooring shackle in the Gulf of Mexico and a second incident involving two sockets in another mooring system, which highlighted faults in the original heat treatment process as a likely cause. A subsequent report by the US Department of the Interior’s Minerals Management Service (MMS) concluded that defective heat treatment during component processing resulted in a metal unable to meet Charpy impact test requirements for material toughness and that testing parameters were either not followed or not adequate to ensure specifications were met.

The MMS recommended that operators should revise their specifications to make sure that testing and manufacturing produces a satisfactory product, which will meet future usage demands. It also commented that operators should review their requirements for both destructive and non-destructive testing of critical elements, as well as ensuring that test coupons, or pieces, are properly representative.

Indeed, it was later found that the test pieces were not samples taken from the actual product and subsequent research indicated the importance of sample positioning in achieving representative and consistent toughness values. Thus, while energy absorption in a longitudinal orientation achieved a satisfactory 70-80 joules, the same test in the transverse direction recorded a disastrously low 4 joules. It was also easier for a smaller test piece of 2” cross-section to pass the impact test, rather than a larger, more representative section.

Through a wealth of metal testing and heat treatment experience, developed over a market history dating back more than 90 years, Keighley Laboratories is perfectly placed to offer independent metallurgical testing, on a sub-contract basis. Its long-established Test House boasts a full array of physical and mechanical testing resources, including room and sub-zero temperature assessment down to -196°C, Charpy impact test and sample preparation provisions, all the main hardness and micro-hardness testing methods, and specialist equipment for tensile and compression loading and determining other key mechanical properties. Accelerated salt spray techniques, humidity chambers, solvent/chemical resistance and other corrosion-related testing are also among its specialised facilities.

A spacious new optical suite houses advanced metallurgical microscopes complete with image capture software, a fully-equipped CNC machine shop, a highly-respected chemical analysis department and a dedicated team of NDT inspectors qualified to PCN Level 2/3, further extending Keighley Labs’ in-house technical resources, establishing it as one of the best-resourced independent metallurgical testing services in the country. Added to which is its undoubted expertise in the heat treatment of metals, including expert consultancy on thermal and quenching processes and the selection of suitable materials at the design stage. The fact that all of these interrelated metallurgical capabilities are available to customers on a single site only strengthens Keighley Labs’ credentials for metallurgical testing of critical components and advising on product quality issues.

Protective covers for industrial connector hoods from Harting #PAuto

Harting has introduced a new range of protective covers which provide optimal protection against dirt for contact inserts in its Han® HPR industrial connector hoods in sizes 6B, 10B, 16B and 24B.

The new covers are designed for use in electrical interfaces in vehicles or in the industrial environment which are subjected to extreme conditions. In order to be able to guarantee reliable transfer of sensitive signals under these conditions, connectors have to be protected against moisture, snow, ice, rocks and other environmental influences. The Han® HPR housing series was developed for exactly such application areas.

Connectors that are not permanently mated are often exposed to these influences without protection. This may result in malfunctions or even serious breakdowns in safety equipment. With the new Han® HPR protection covers, Harting has expanded the Han® HPR housing series product range, which is widely used in the rail sector.

The covers are equipped with the screw/toggle locking system commonly used in the Han® HPR housing series and offer IP 68 protection as specified by IEC 60529. An attachment cord connects the Han® HPR protection cover securely to the housing so that it cannot be lost.

Control system for municipal water treatment plant in Indonesia

Yokogawa  has received an order from PT Waskita Karya (Persero) Tbk, a major Indonesian construction company specialising in the power plant and water supply and wastewater treatment sectors, to supply the automation system for the Petanu water treatment plant that it is building at the Sanur beach resort area on Bali's southeastern coast for a municipal water utility that is overseen by the Indonesian government's Ministry of Public Works.

Sanur is in the South East!
The Petanu water treatment plant will produce 300 litres per second (approximately 25,920 cubic metres per day) of clean water for Gianyar Regency, Denpasar City, and Badung Regency. It is scheduled to start operation in September 2013.

Indonesia is the world's fourth most populous country, and its infrastructure is being rapidly developed to meet the growing needs of its urban population and the tourism industry. The Petanu water treatment plant is a key to ensuring a stable supply of clean water for southeastern Bali.

The automation system that is to be installed at the Petanu water treatment plant includes the FAST/TOOLS SCADA (Supervisory Control & Data Acquisition) software package, the STARDOM(TM) network-based control system, analysers, and a variety of field devices such as ADMAG series magnetic flowmeters. Yokogawa Indonesia will be responsible for the entire project, from engineering to delivery, installation, and commissioning.

Yokogawa was able to win this order because of its ability to provide a “one stop” solution comprised of field devices, control systems, and other products that will meet a wide range of operation and maintenance needs and thereby improve the efficiency of water production.

Water shortages are becoming a serious problem in many parts of the world, particularly in developing countries, because of rapid economic and population growth. According to a report entitled “Future vision and policy response toward water business industry" (pdf) that was released by the Japanese Ministry of Economy, Trade and Industry in April 2010, the global water market is projected to grow from 36 trillion yen in 2007 to 87 trillion yen in 2025.

Encouraged by the success in winning this order, Yokogawa will seek to expand its share of the water-related control business in Southeast Asia and other emerging regions by providing water supply infrastructure solutions based on its extensive experience in water treatment applications and technical expertise in automation systems.

Transmit CAN data quickly & reliably via Bluetooth

The robust, secure solution for wireless CAN communications, specifically for industrial applications

IXXAT offers a universal bridge, gateway, and PC interface solution for the wireless networking of CAN components and systems in a new and improved version.

With three modes provided, the user can now adapt data communications optimally to the specific application in terms of latency, data throughput, and fault tolerance. In SHORTEST_LATENCY mode, latency times averaging 4 ms can be achieved, while QUICKEST_CONNECTION mode permits secure data transmission even in CAN systems running at 1 MBit/sec and 100% bus load.

A typical application for CANblue II is the wireless connection of CAN segments via Bluetooth and wireless system access using a notebook or handheld service unit. However, areas where an extremely reliable connection is required, such as the networking of rotating or mobile system parts, can also be implemented using CANblue II. Thanks to the use Bluetooth technology, built from the ground up on encrypted transmission mechanisms that are resistant to external interference, CANblue II is perfect for this kind of application.

Bluetooth's FHSS process, also used in CANblue II, changes the frequency at which messages are transmitted about 1600 times a second. If one of the 79 channels used experiences interference, this fault is detected and the message is resent in another frequency range. The available bandwidth thereby is used very sparingly, so that multiple different Bluetooth systems can work in parallel without noticeably interfering with one another.

The problems caused by overlapping WLAN systems and the limited number of WLAN channels, also considering the required channel spacing, is nearly unknown in Bluetooth. Even WLAN systems overlapping with Bluetooth in the immediate vicinity only interfere with the operation of the Bluetooth network to a negligible extent, since only a few of the 79 Bluetooth channels overlap the WLAN frequency band. Thus at most the transmission performance of an overlapping system, whether WLAN or Bluetooth, may be reduced due to the message retransmissions required.

Used as a bridge, CANblue II units transmit their data transparently over the secure Bluetooth connection. In addition to pure CAN applications, this permits applications to be implemented using higher protocols (CANopen, DeviceNet, SAE J1939) and customer-specific protocols. For use on the PC a powerful Windows driver is available. Applications based on other operating systems (e.g. Android, Linux, INtime, QNX) or customer-specific hardware can be implemented using an open ASCII protocol. There is also an Android sample implementation available.

Its broad power supply voltage range of 9 to 30 VDC, compact construction, and fastening holes in the housing all simplify the integration of the device into existing systems. The CAN interface is implemented in compliance with ISO 11898-2 and has a DSub 9 connector that meets the requirements of CiA 303-1. Upon request, the CANblue II can also be provided in an IP67 variant.
The CANblue II is available with an internal or external screw-on antenna that supports transmission distances of up to 300 meters, depending on spatial conditions. The radio signal quality can be read out using Bluetooth to monitor the connection quality.

Battery-powered system for remote circuit breaker racking

Remote Solutions has introduced the Safe-T-Rack® (STR®) SR-U Battery-powered Remote Racking System. This lightweight and portable system helps ensure compliance with evolving arc flash mitigation regulations and bring operation of low and medium voltage electrical circuit breakers, motor starters, loadbreak switches, vault switches, network switches and Load Tap Changers (LTCs) to a new level of safety.

The U.S. Occupational Safety and Health Administration (OSHA) recognises hazards associated with arc flash incidents as defined in the National Fire Protection Association (NFPA) 70E standard. An arc flash is part of an arc fault, a type of electrical explosion that results from a low-impedance connection to ground or another voltage phase in an electrical system. Experience has shown that Personal Protective Equipment (PPE) has limited effectiveness in safeguarding workers from arc flashes during operation and racking of switchgear equipment commonly used at power plants, electrical transmission & distribution facilities, mining operations, refineries and petrochemical plants, and other industrial and commercial sites.

Application of an effective remote racking system increases distance from the source of the arc fault to the operator and eliminates manual contact while breakers are being inserted or removed.

Safe-T-Rack® is a fully automated, American National Standards Institute (ANSI)-tested tool that has redefined techniques for circuit breaker remote racking and control. The latest addition to the STR® line, the SR-U Battery-powered Remote Racking System, is a lightweight and portable solution employing a Mil-Spec design and robust self-diagnostic capabilities. The system offers best-in-class features such as: rechargeable 28V battery powered for international use, universal handheld controller and drive unit, quick-change tool coupling, smart drive bracket design, and an endlessly expandable data-bus design. The unit includes a standard 50-foot cable with optional extensions.

According to Remote Solutions President Bob Stevenson, the portable SR-U Battery-powered Remote Racking System is a reliable and cost-effective alternative to "land-based" remote racking systems, which are prone to malfunction when racking an improperly positioned device. Alignment issues can result in physical damage to the circuit breaker, rendering it unserviceable.

"Our SR-U system is designed to increase operator distance from the breaker, allow racking in and out of a cubicle, minimise damage from mechanical racking failures, and integrate remote operation of breaker open/close functions, Users no longer have to worry about de-coupling or jamming the breaker into its cubicle, requiring that the bus be de-energised to safely remove and repair the equipment."

Remote Solutions specifically developed the Safe-T-Rack® product family to provide users of low and medium voltage circuit breakers, including GE vertical lift (MagneBlast) designs and a variety of horizontally racked breakers, a comprehensive alternative to arc flash protection garments. Safe-T-Rack® systems are engineered to easily integrate with original equipment switchgear and allow equipment operators to distance themselves from an arc flash incident. This patented technology revolutionises the way circuit breakers, motor starters, loadbreak switches, vault switches, network switches and LTCs are racked in/out of service and charged, closed and opened.

Passive fire shelter technology provides protection choice for process plant designers

Outdoor enclosure specialist Intertec now offers an extensive range of fire-resistant shelters, including ‘1709’ models designed to protect critical safety equipment from exposure to high temperature fires in hazardous areas. The shelters are entirely passive, maintenance-free and impervious to a wide range of corrosive chemicals – including salt, sulphur dioxide and sour or acid gas.

Typical applications for the 1709 versions include protecting valves and actuators in the emergency shutdown and fire fighting systems of refineries and chemical plants, and offshore oil and gas production platforms.

Another key application for Intertec's fire protection materials is separating hazardous and non-hazardous areas on ships and on offshore drilling, processing and storage platforms. This development will be of considerable interest to designers seeking a means of meeting the future IEC 61892-7 standard for offshore platforms and vessels, which will demand area separation materials capable of withstanding a hydrocarbon fire for between 60 and 120 minutes.

Intertec has extensive experience of fire resistant shelters, having produced models tested in accordance with the German DIN 4102-2 standard for 20 years. Throughout this period the company has continually improved materials and construction techniques to meet more challenging specifications, culminating in a new patented design that keeps contained equipment below 60 degrees C (140 F) for 90 minutes, even during ‘rapid rise’ hydrocarbon fires that can reach 1,093 degrees C (2,000 F) within five minutes. This level of protection is believed to be unique for passive fire shelters – many competitive models only specify 30 minutes of protection.

"Our fire-resistant shelters provide significant technical advantages to process plant safety designers," says Intertec's Martin Hess. "They provide an extended safety margin of up to 120 minutes, but without the drawbacks of other fire-protection technologies such as metal cases, intumescent coatings, blankets and bags. They are rigid, so they can incorporate easy-open access points for maintenance, yet they are also exceptionally light and can be mounted directly on pipework."

There are no specific international standards for fire shelters designed to keep contained equipment below 60 degrees C, so Intertec has defined rigorous test procedures. The company’s standard fire shelters are designed to withstand the type of fires that can occur in business and residential buildings, which are relatively slow burning; they typically take about 30 minutes to reach 800 degrees C (1,472 F), eventually reaching a maximum of 1,100 C (2,012 F) after about 3 hours. The shelters are tested against the standard nominal time-temperature curve that is defined in ISO 834 and used in many fire protection standards, and are available with ratings of 30, 60, 90 or 120 minutes.

Intertec’s 1709 fire shelters are designed to withstand hydrocarbon fires with a ‘rapid-rise’ time-temperature curve. This curve is also used in the ANSI/UL 1709 standard for the protection of structural steel, which plant designers tend to use as reference because of the lack of alternatives. However, the permissible temperature for structural steel is 550 degrees C, because the metal retains its integrity up to this level. Intertec’s 1709 fire shelters, on the other hand, are designed to keep valves, actuators and electronics operational by preventing their temperature exceeding 60 degrees C throughout the protection period. The shelters’ design has been verified by an independent agency, which confirmed that its protection period exceeded 90 minutes, and that during this time the surface temperature of a sample electrical actuator in the shelter did not rise above 55 degrees C (131 F).

Intertec fire shelters are constructed from a proprietary composite material comprising one or more layers of fire resistant mineral wool ‘sandwiched’ between sheets of advanced glass reinforced polyester (GRP). Depending on the model, the walls may consist of a single or double sandwich of this composite material. GRP has major advantages over metal, which is used in many conventional passive fire shelters. It has an excellent strength/weight ratio – GRP is almost as strong as stainless steel, but four times lighter – and is highly resistant to weathering and the corrosive effect of salt and other aggressive chemicals, as well as to most common petrochemicals. It is also an electrical insulator and has a much higher thermal resistance than metal, which makes it easy to avoid condensation. These attributes make the material ideal for the external and internal walls of fire shelters intended for long-term use in harsh environments, especially when weight is a consideration, such as offshore.

The composite material used for Intertec’s 1709 fire shelters incorporates multiple layers of mineral wool and other fire resistant insulators, together with special fire retardant mineral coating. This material is the result of extensive development by the company and is specifically designed for graceful degradation, to ensure that cabinets and shelters maintain their mechanical integrity and thermal insulation properties for as long as possible in a fire.

The inherent rigidity and low weight of the construction material makes it ideal for shelters that are designed to be directly supported by process pipes, or for larger enclosures intended to accommodate non fire-safe valves as well as their actuators. For maintenance purposes, shelters can incorporate removable panels – these facilitate much faster access than other common forms of fire protection which helps to minimize service time and costs.

"Operator interface that just works, Mate!"

New option to run groov® mobile HMI on a PC or server is ideal for IT professionals and OEM machine builders.

groov Server for Windows™ is a software-based version of Opto22 groov product for building, deploying, and viewing simple, effective, and scalable operator interfaces to monitor and control systems and equipment using computers and mobile devices. groov Server for Windows runs on enterprise PCs or servers, and is intended for settings where the IT Department won't add hardware to the network, but will add software served from a Windows PC. Since groov Server for Windows runs on a PC, it also reduces costs for OEM machine builders who incorporate a PC in their product and need to add mobility options for their HMIs.

Browser-based Benefits
Using only a modern web browser, groov securely lets industrial automation end-users, system integrators, machine OEMs, building managers, technicians, or any authorized person quickly build and deploy browser-based interfaces for automation, monitoring, and control applications. Although groov is served from a Windows PC, any computer with a modern web browser can be used to build interfaces. These operator interfaces can then be viewed on almost any computer or mobile device regardless of its manufacturer or operating system, including PCs, tablets, smartphones, and even smart high-definition televisions. groov is intended to augment traditional human-machine interfaces (HMIs) by making important information available at any time and in any location.
groov offers a simple yet flexible environment for developing operator interfaces with zero programming, and requires no per-seat runtime or viewing licenses. Overcoming the biggest challenge in developing for multiple screen sizes and mobile HMIs, groov automatically and gracefully scales all screens, page objects, and gadgets, allowing groov HMIs to be viewed and manipulated from virtually any device of any screen size.

groov works with modern web browsers like Internet Explorer, Firefox, Chrome, Safari, or Opera running on operating systems including iOS, Android, Microsoft Windows, Mac OS, and Linux. groov benefits from the capabilities of these browsers by using the latest web standards like HTML5, CSS3, and SVG. And while many competing technologies depend on additional software or browser plug-ins like Flash, Silverlight, or Java to work, groov simplifies deployment by requiring no additional software or plug-ins.

Networking and Interface Development
groov Server for Windows runs on a PC or server that you control. All network communication between a web browser and groov uses an encrypted secure sockets layer (SSL) over an HTTPS connection. groov does not respond to any other communication methods on any other ports.
groov connects to Opto 22 SNAP PAC automation systems and OptoEMU energy monitoring products over a wired Ethernet network or wireless LAN. Opto 22 recommends using a separate network interface card (NIC) to segment your control systems. Support for the OPC-UA protocol is planned in 2013 and will allow groov to communicate with systems from other manufacturers that offer an OPC-UA server.

The simple and flexible development environment, groov Build, dramatically reduces the time needed to build interfaces when compared to traditional HMI screen-building tools. groov Build includes a library of scalable, touchscreen-ready gadgets: gauges, buttons, range indicators, text entry, sliders, and trends. Images and real-time video from network IP cameras—also fully scalable—can also be added. Designed to support HMI best practices, groov Build includes the tools necessary to build high-performance, intelligible information and control screens like those defined by the High Performance HMI Handbook (Hollifield et al.) and the ASM (Abnormal Situation Management) Consortium Guideline, Effective Operator Display Design.

Energy harvesting battery life extender.

Tthe LTC3330 is a complete regulating energy harvesting solution, from Linear Technology, that delivers up to 50mA of continuous output current to extend battery life when harvestable energy is available. It requires no supply current from the battery when providing regulated power to the load from harvested energy and only 750nA operating when powered from the battery under no-load conditions.

The LTC3330 integrates a high voltage energy harvesting power supply, plus a synchronous buck-boost DC/DC converter powered by a primary cell battery to create a single non-interruptible output for energy harvesting applications such as those in wireless sensor networks. The energy harvesting power supply, consisting of a full-wave bridge rectifier accommodating AC or DC inputs and a high efficiency buck converter, harvests energy from piezoelectric (AC), solar (DC) or magnetic (AC) sources. The primary cell input powers a buck-boost converter that operates from 1.8V to 5.5V at its input when harvested energy is not available to regulate the output whether the input is above, below or equal to the output. The LTC3330 automatically transitions to the battery when the harvesting source is no longer available.

The LTC3330’s energy harvesting inputs operate from a voltage range of 3V to 19V, AC or DC, making it ideal for a wide array of piezoelectric, solar or magnetic energy sources. Its input undervoltage lockout threshold settings are programmable between 3V and 18V, enabling the application to operate the energy harvesting source at its peak power transfer point. Other features include programmable DC/DC and LDO output voltages, buck-boost peak current limits, supercapacitor charger/balancer and an input protective shunt (up to 25mA at VIN >20V).

The LTC3330EUH is available in a 5mm x 5mm QFN package. Pricing starts at $3.55 each for 1,000-piece quantities. An industrial temperature grade version, the LTC3330IUH, is also available.

Process control system improves production processes in the dairy industry!

Easy management of materials, system parameters, orders and storage locations; integrated data management ensures product quality and traceability from the raw milk to the saleable product

The Dairy Functional Toolset (DFT), from Siemens, complements the Simatic PCS 7 process control system by adding various important functions for milk-processing enterprises. DFT allows specific workflows such as milk sampling, pasteurization, separation, cheese and yoghurt production and the end-of-process cleaning of pipes and tanks to be accurately and easily controlled.

The new DFT software contains all necessary visualizations (faceplates) for displaying plants and processes controlled by Simatic PCS 7 on the screen. Important process steps are pre-installed to the most up-to-date industry standards and can easily be configured to suit any application. Moreover, this Siemens DFT toolset continuously captures and archives production-related data such as temperature, agitation time, pH, and storage location. These data can then be exported to a superimposed MES (Manufacturing Execution System) or an ERP (Enterprise Resource Planning) system. This integrated data management concept ensures consistently high product quality and product traceability from the raw milk to the processed, saleable product.

Functions related to specific process steps and workflows are pre-consolidated within the DFT software. For example, modules for the management of materials, system parameters, orders and storage locations are pre-installed. These support the automation of production processes from the delivery of the raw milk to the signing off for bottling and packaging. Further modules such as those for tank management, piping system management, process line management, follow-up material testing and a CIP (cleaning in place) sequencer have been optimized within the new software with a view to automating processes such as transfers, mixing and cleaning.

Milk processing today calls for extremely efficient and perfectly interacting processes from the delivery of the raw milk and its sampling and initial preparation through the various operations in the dairy processing plant to its packaging, storage and shipment. With its customized solutions such as the DFT software and an extensive product portfolio of integrated automation and drive solutions, Siemens is helping milk-processing enterprises to optimize their production processes and thus enhance their competitiveness.

Preliminary specification for ISA100.11a transducer block

The Fieldbus Foundation has issued a FOUNDATION fieldbus Preliminary Specification (PS) addressing fieldbus transducer blocks for ISA100.11a wireless devices. ISA100.11a is an industrial wireless networking technology standard developed by the International Society of Automation (ISA).

As part of the FOUNDATION for Remote Operations Management (ROM) solution implementing wireless and remote I/O, the new technical specification defines a fieldbus transducer block used within FOUNDATION for ROM devices to communicate with ISA100.11a instruments. In addition, it describes the method for configuring tools and asset-managing hosts to access ISA100.11a devices, as well as structures to identify and maintain device status in ISA100.11a networks connected to FOUNDATION for ROM devices.

The new transducer block specification will enable automation end users to interface ISA100.11a devices to FOUNDATION fieldbus for better integration with a control system, or with FOUNDATION devices. The technology also supports a networked method for asset-managing hosts to access an installed base of ISA100.11a devices for configuration and maintenance purposes.

HSE provides an efficient way to bring large concentrations of discrete and analog field I/O from modular devices back to the control room using a high-speed HSE connection. Employing HSE equipment functioning like a smart remote terminal unit (RTU), the technology brings all forms of conventional I/O into the native fieldbus environment easily. This solution makes discrete I/O, analog I/O, H1 fieldbus, HART® and WirelessHART® available over common Transport Control Protocol/Internet Protocol (TCP/IP) networks. The addition of the new ISA100.11a transducer block further expands the integration of process instrumentation within a FOUNDATION control system infrastructure.

Access to FOUNDATION technical specifications is a key benefit of Fieldbus Foundation membership. The specification is available free for review by foundation members, and can be accessed in the Preliminary Specifications area of Fieldbus Forums. During the review cycle, anyone identifying private rights (i.e., patents, copyrights and trademarks) within the specification should contact the Fieldbus Foundation
