Safety of insulated supplies!

PMD s20 has now been added to the portfolio of electronic monitoring relays in the PMDsigma series from Pilz. With it, it is simply turn and click to set all the values, which can then be stored on a chip card. This gives users the flexibility to transfer data for other devices.

PMD s20 monitors the electrical safety of insulated supplies – for operating theatres, offshore installations or the electroplating industry for example – and prevents power failures due to short circuits.

Insulation monitors PMD s20 monitor the insulation resistance of unearthed AC/DC systems, simply and reliably. De-energised systems can also be monitored thanks to a separate supply voltage.
Normally energised and normally de-energised mode can be freely selected via two relay and analogue inputs.

The device is quick to assemble via spring clips, so there is no need for tools. All values are set simply and securely via a rotary encoder with key function. Set-up and commissioning times are reduced as a result.

Support for parameter setting is menu-driven on a plain text display, which also provides user-friendly diagnostics. All values can be set, displayed and called up via the display. An up-to-date measurement of the insulation resistance can also be shown permanently on the display. Once the values have been created, they can be stored on a chip card. This saves time and effort during commissioning and when exchanging units.

All setting elements are covered to protect them from unauthorised access, thereby offering increased protection against manipulation.

Insulation monitors PMD s20 have a universal power supply and are therefore suitable for universal use.

Automation offerings at Hannover

The Siemens Industry Automation Division will be present at this year’s Hanover Fair with an array of worldwide leading products and innovations for the seamless automation of industrial processes. “Our comprehensive automation engineering and industrial software portfolio is designed to provide solutions to the most urgent challenges facing our customers in terms of improving productivity, flexibility and security, cutting costs and reducing the time to market”, explained Industrial Automation Systems Business Unit CEO Ralf-Michael Franke at the pre-show press conference. “There is clearly an increasing need for efficient industrial software among our customers. By linking industrial software with our leading-edge automation engineering under a single roof we become the pacemaker in the marketplace.”

Siemens has extended its portfolio of software solutions for manufacturing industry both by making strategic acquisitions and through its own internal development, and today is in a position to provide a complete software portfolio from product design through to production control. Its experience in the integration of industrial hardware and software has been brought to bear in the “Totally Integrated Automation Portal”, an integrated engineering framework launched back at the end of 2010. Alongside the TIA Portal, technological highlights from Siemens Industry Automation to feature at the Hanover Fair will include product innovations designed to boost energy efficiency and productivity. Franke on the TIA Portal: “This represents a further development of our worldwide leading Totally Integrated Automation portfolio, one which will help to power our customers forward into a whole new era of intuitive engineering.”

There are already plenty of Siemens customers enjoying the beneifts of major engineering cost savings with the optimized workflow made possible by the new TIA Portal framework, equating to a reduction of 25 per cent in concrete projects. Franke sees the TIA Portal as a significant step but only the first of many in a process of further software development which is set to stretch forward to the year 2030. “We are working towards the achievement of completely integrated product and production engineering. The complete integration of what are today two completely separate workflows will open up growth opportunities for us, and enormous additional productivity potential for our customers”, explains Franke. Calculated on the basis of project examples, the potential for cost savings is estimated to be a further 20%.

Alongside the growing relevance of industrial software as one of today’s driving trends, the issue of plant security has taken on ever greater significance over the past year. Plant operators right across the industrial spectrum are increasingly concerned about the issue of security, as open communication in the industrial environment and ever greater networking of production systems render industrial plants vulnerable to attack. Franke believes a comprensive system of security management to be vital to the safe operation of modern plant and machinery: “Plant operators need to look at security as an integral solution – from know-how and integrity protection through to the prevention of industrial espionage and sabotage”. Siemens offers its customers specific security products designed to improve plant protection. The portfolio on show in Hanover ranges from products with integral security properties through to advisory services and implementation of comprehensive security solutions.

Siemens at the Hanover Fair 2011: In keeping with the theme “Create Sustainable Value”, at booth A72 in Hall 9, Siemens will be demonstrating how economic efficiency and productivity can be reconciled with ecologically responsible industrial production. It will also be informing its customers right across the different fields of industry about how to create sustainable added value with solutions from Siemens.

Modular concept industrial PCs

Modular Concept with Powerful Industrial PCs

With its Valueline product line, Phoenix Contact is offering a modular concept for process visualization, robotics, and industrial automation at a favorable price based on powerful, maintenance-friendly industrial PCs. The industrial PC base unit can also be configured as a classic panel PC with a display and various mounting options. It can be used at ambient temperatures of up to 55 °C.

To expand the range of functions — such as the integration of a security function in the form of an FL MGUARD PCI router — both the base unit and the panel PC can be expanded by two PCI slots. Complex processes can be visualized on the TFT touchscreen displays with sizes from 12” to 24” diagonal.

The IPCs are based on a cooling concept without fan. Combined with various processors from Intel ATOM 1.6 GHz, Celeron 1.01 GHz, up to Core2Duo 1.5 GHz CPU, all of them can be used in demanding and energy-efficient areas. The service-friendly design of the industrial PCs allows simple and fast access to important components, such as the interchangeable hard disk or the CMOS battery.

A modular production technique facilitates fast delivery times and a favorable price — even for customized configurations.

Shear beam load cells

NEW LCJA Shear Beam Load Cells
Omega has expanded its capabilities by introducing a new range of shear beam load cells. This new range overcomes the disadvantages seen by using lower spec bending beam models. They have a load range of 250kgf to 9 tonnes, have a high side load rejection of 500:1 and faster return to zero after load removal. Additionally, they have the added capability of a higher tolerance of dynamic forces and vibration. Each device is supplied with a FREE traceable calibration certificate. They are corrosion resistant and have an IP67 rating making them ideal for wash down application.

Higher voltage power-supply units have full remote interfaces

The new PLH-P series from Aim-TTi are higher voltage linear regulated laboratory power supplies fitted with a wide range of remote control interfaces.

Available as 0 to 120 V or 0 to 250 V models, the PLH-P series provide more than 90 W of power from a highly compact quarter-rack form factor.

Fully opto-isolated analogue remote control is incorporated using a scale factor of either 0 to 5 V or 0 to 10 V.  Digital remote control is provided by USB, RS-232 and LAN interfaces with GPIB available as an option. The LAN interface is LXI compliant.

The PLH-P series uses special safety binding post terminals, designed by TTi. These are touch-proof to over 250 V and can be used with fixed shroud 4 mm plugs for laboratories that make their use mandatory. However, they can also accept standard 4 mm plugs, spade connectors or bare wires for general-purpose use. Power and sense terminals are duplicated on the rear panel for rack-mounted applications.

The command set is compatible with other TTi power supplies including the QL, PL, QPX and CPX. An IVI driver provides support for common high-level applications such as National Instruments LabView or LabWindows, and HP/Agilent VEE.

Water security in the US

Advanced monitoring technology helps improve water security

As part of the homeland security activity in the United States, their Environmental Protection Agency (EPA) continues to test commercially available water quality sensors for their ability to provide a warning alarm due to deliberate or unintentional contamination events within a drinking water system. The Intellisonde™ in-pipe water quality monitor from Intellitect Water is one of several instruments being assessed by the US EPA in a simulated network at its Ohio Test and Evaluation Facility.

The project's work on water quality sensors is in support of the Water Security Initiative, which is developing contaminant warning systems and addressing the risk of intentional contamination in drinking water distribution systems.

The trial with the Intellisonde has been underway for over a year. Summarising the Intellisonde’s™ preliminary results, the EPA's John Hall says; “We have monitored a number of parameters such as pH, Conductivity, ORP and Temperature, however, the Chlorine and Flow data have proved to be particularly useful. Free Chlorine levels, for example, are significantly affected by a broad range of contaminants and the flow data can be used to reduce alarms due to operational events.

“Overall, the Intellisonde™ has provided reliable chlorine data for over 6 months without changing the probe, which represents an improvement in this principle of detection. Wide-spread deployment of solid state chlorine probes within the US water distribution network will be dependent largely on the reliability of the data and the cost of operation and maintenance for the sensor.

“Additionally, the Intellisonde™ has been easy to use once aligned in the pipe properly and we look forward to reporting further findings as the project progresses.”

Developed to continuously monitor up to 12 parameters within drinking water distribution networks, the Intellisonde™ is a small water quality monitor that can be inserted into pressurised pipes through a 1½ inch valve. Measurement options include Free Chlorine, Total Chlorine, Mono-chloramine, Dissolved Oxygen, Conductivity, pH, ORP/Redox, Flow, Pressure, Temperature, Turbidity and Colour. Importantly, none of these requires membranes or reagents and the sondes can be deployed for long periods without the need for frequent recalibration or maintenance.

Production of glass containers for pharmaceutical use

SPAMI, a company forming part of the Stevanato Group, has developed an inspection system to improve the quality of glassware. It uses quality control technologies to screen the glass tubing on arrival at the plant as well as the final product. The system includes a visual inspection system (NoVIS), a system for continuous temperature measurement, and also a digital image processing system, called CLEANER, which is able to detect and remove defects in the glass as small as a few microns in the final product. The fully integrated process machinery provides measurement of glass tube diameter, wall thickness, and temperature using infrared pyrometers (Pyrometer Annealing control) for total quality control, and motorized burners provide close control of their positioning. The use of this system gives Stevanato their advantage in quality over other vial manufacturers. For this advanced system, S.P.A.M.I. uses HMS Anybus converters for the connection between remote visual inspection cameras and the PLCs controlling the production lines
Founded in 1949 as an artisan workshop in a region with a strong tradition in the art of glass-making, Stevanato Group is now an established industrial enterprise producing high technology systems.

The group comprises two divisions. The Glass Division specialises particularly in the production of primary packaging of glass tubing for pharmaceutical use. It offers a wide range of products from the most traditional primary packaging, such as ampoules and vials, to rapidly growing products such as cartridges for self-injectors and peninjection systems, including sterile ready-to-fill syringes.

The Engineering Division, made up of the companies S.P.A.M.I. and Optrel, focuses on the design and production of machinery and equipment for the conversion, visual inspection and monitoring of glass tubing containers. The synergy between the two divisions ensures that the Stevanato Group has full control over the entire production process, from the purchase of the raw materials right down to after-sales support.

“S.P.A.M.I.’s production is intended both for the companies within the group and for sale to other external companies.” T
he mechanical and electrical solutions installed on the forming machines have been designed to provide the greatest precision and the best results in the production of glass containers.

All the components used to form the molten glass are installed and carefully checked to guarantee the dimensional tolerance of vials, syringes, cartridges and ampoules. The components installed in the forming machines and conveyor belts have been specifically selected to avoid contaminating the containers. The process is fully automatic, from the loading of the tube to boxing.

The production cycle starts with the glass tubing which is acquired externally in pieces of approx. 1.5 m in length and with an appropriate diameter for the size of the finished product. The glass tubing is fed into rotary forming machines with several processing heads and is heated by burners. Depending on the processing cycle, which is selected according to the product to be made, the mouth and the bottom of the vial, ampoule, syringe, etc. are formed in this way.

The following equipment is installed on the line:
Downstream of the forming machines is a conveyor belt where dimensional and cosmetic inspections are carried out by means of cameras to ensure a thorough check of the glass containers. “These are basically dimensional measurements carried out by analyzing the image”, Gobita explained. “Since the product is subject to mechanical stress during processing, there is also an annealing oven providing a heat cycle to eliminate the tension formed in the glass.” Then the final stage comprises quality control of the finished product and automatic packaging. It should be noted that this final part of the cycle is carried out in such a way as to ensure the levels of quality and sterility required for use in pharmaceutical applications.

There are a number of competitors on the market that operate at international level. “Our main competitors are German and American, whereas the other companies in Italy are much smaller than ours."

The value added offered by S.P.A.M.I. is to be found primarily in the quality of its products, which has enabled it to excel in this sector.  "Since they are used in pharmaceutical applications, our products have very high quality requirements and have to comply with very stringent regulatory limits. This requires a large number of very qualified Quality Control staff”, continued Gobita. “The difference between us and our national competitors can be seen in this very aspect. Our capacity for research and development is also a factor: when pharmaceutical companies ask us for trial products that are different from the standard products, we can do the product design because we can modify our systems. Just like the mechanical division which produces the systems within the group, S.P.A.M.I. can modify and adapt these systems to suit production requirements. This ability to customize systems is another important value added we can offer our customers. It should be remembered that there are a number of standard products in the pharmaceutical sector, such as ampoules and vials that we all know about, but there are also many special products - and their numbers are increasing - that for the most part are developed ad hoc. In these cases, a specific machine is needed, so in the majority of cases a pre-existing machine has to be modified”.

A positive collaboration with HMS
The association with HMS came about in order to resolve a specific communication problem.

An application was developed by the mechanical division to carry out a series of product quality checks based on machine vision technology. More specifically, Cognex smart cameras had to be connected to Siemens PLCs. “We thus needed to enable cameras with Ethernet interface to communicate with PLCs with Profibus protocol”, explained Gobita. “After some careful research, and through EFA Automation, the exclusive distributors in Italy of HMS’s GATEWAY solutions, we singled out the Anybus devices which enabled us to solve the problem of communication between our equipment.”

Other potential suppliers were considered at the time, but HMS was the only company that could offer a wide range of protocol converters. “This widespread availability was central to our choice, because our various applications are often very different from each other. Initially, for example,
we needed to manage the Profibus protocol since it was used by Siemens PLCs, but our company normally also uses programmable controllers from other suppliers. So it is essential for us to have an extensive product range.”
The first HMS product used was a device from the range of Anybus converters that converts from Profibus to Modbus on Ethernet: the Anybus X-gateway.

More than one Anybus converter may be installed on each production line. “Up to now we have used a number of converters, because the application has been used in various systems”, continued Gobita. “Smart cameras are used to check the product’s various quality aspects and must be installed in several different points in the system. Basically, this is not a “one-off” application of HMS converters, but an application that has become standard for us. We are very satisfied with our choice. HMS’s Anybus products are very sound, functional and simple to use compared to other similar devices that we tried. We all know that while it’s very easy to find complex things, it isn’t so easy to find simple things.

We haven’t had any problems and the way things have developed is also down to this. In the future we plan to use the HMS Anybus converters also on other lines, where they will of course be closely linked to our control systems via cameras. And, since standards require increasingly narrow tolerances, it is inevitable that checks by means of remote cameras will increase”,
concluded Gobita.

Busbar improvement

Design Improvements for Rittal’s RiLine60 Busbar Technology

Easier assembly of busbar systems will save time and money using Rittal’s RiLine60 busbar technology for the construction of low-voltage switchgear. Design improvements to the busbar supports mean that the integrated step mechanisms for adapting to the flat bar cross-section can now be locked using pins. Engineers have the flexibly to insert flat copper bars retained in a holder from the front, or slide them in from the side.

Further improvements relate to assembly and the cable entry of busbar connection adaptors. Creating holes by simply knocking out perforations permits the simple, tool-free introduction of round conductors and laminated copper bars. The specially incorporated anti-slip guard also guarantees that the OM (One Move) component adapter holds securely in any position. Installation on 4-pole busbar systems is ensured by adjusting the adapter section.

The devices belong to a new product line of particularly compact and energy-saving industrial PCs in the nano-format.

The Atom processors of the power-optimized E6xx series from Intel form the basis for the new Simatic IPC227D Nanobox PC and Simatic HMI IPC277D Nanopanel PC embedded industrial PCs from the Siemens Industry Automation Division. The power-optimized Atom processors offer high-speed data processing and communication with low heat dissipation and a power consumption starting at just eight Watts. The devices boast high resistance to vibration and shock and have an integral 24 Volt industrial power supply unit. For maintenance-free use – for example in machine building, marine applications or in building or traffic control systems – the units can be operated without fans at ambient temperatures of up to 50 degrees Celsius. Compact-Flash cards with up to eight GB capacity or solid-state drives (SSD) of up to 50 GB can be used as robust bulk storage devices. As an option, Siemens offers a 250 GB hard disk for the Nanobox PC. Likewise, a retentive memory of up to 512 KB can be integrated if required and also used for applications without batteries. Within the buffering period, 128 KB of data can be written, for example to back up important machine data in the event of a power outage.

The Simatic IPC227D Nanobox PC with its compact dimensions of 191x100x60 mm (WxHxD) fits not only inside small control cabinets but also directly into a machine or the machine base. It can be installed very flexibly in the four standard versions of DIN rail, wall, portrait or landscape mounting. All interfaces are located on one side to simplify the connection of cables to the device. The unit can be operated without a fan at ambient temperatures of up to 50 degrees Celsius in almost any installation position. In the basic configuration, the Nanobox PC is completely maintenance-free, thanks to its dustproof enclosure and the absence of battery, fan or hard disk. For expansion purposes, the IPC227D has the option of one PCIe slot, three additional serial interfaces or four digital inputs and outputs (24V DC). For fast device diagnosis, the Nanobox PC has four status LEDs, three of which are fully programmable. Diagnostic software is pre-installed to provide comprehensive analysis.

The Simatic HMI IPC277D Nanopanel PC is available with 7", 9" and 12" high-resolution industrial touch displays in widescreen format, with a wide viewing angle. Devices with larger display sizes are currently being developed. Thanks to LED backlighting that is dimmable up to 100%, the power consumption of the Nanopanel PCs can be significantly reduced.

In all its versions, the IPC227D is equipped with four USB-2.0 ports, while the HMI IPC277D has at least three. Both devices have two Gigabit-Ethernet ports with teaming capability, of which one can optionally be used as a Profinet interface with real-time functionality. An RS232 interface is available as a serial port. Versions of the Nanobox PC with an RS485 or CAN interface are also available as options. By means of the Wake-on-LAN function, the devices can be remotely switched over from the active state to the standby mode, thereby reducing the energy consumption of the computer.

The Industrial PCs can be configured online and can be supplied on request with a pre-installed and activated operating system – Microsoft Windows XP Professional or Windows Embedded Standard 2009 – and have assured long-term availability. Versions with Windows 7 and Windows Embedded Standard 7 are currently under development. Ready-to-run packages including SIMATIC WinCC V11 visualization software or WinAC RTX (F) 2010 control software, which is also available in a fail-safe version for use where the most stringent safety requirements apply, are also being developed.

Monitoring shaft seal and stator temperature of a submersible pump motor

Marsh Bellofram launches fully submersible shaft seal and stator temperature monitor and relay for OEM, industrial and wastewater pump motors

The ATC Diversified Electronics division of Marsh Bellofram Corporation has launched the SPM series, a dual function alarm and relay, designed to monitor shaft seal and stator temperature of a submersible pump motor, providing early warning of machinery failure to reduce downtime and maintenance costs.

The Marsh Bellofram SPM series is designed to operate from a 120 VAC supply voltage, with reliable operation over 10 million continuous duty cycles. The series detects leaks by either resistive float switch or a pair of conductive probes installed in the seal cavity, while over-temperature is detected by a normally-closed low-temperature switch that is mounted on the stator, with LED’s that indicate green for “normal” and red for “leak” and “over temperature” condition values. The SPM series also incorporates the use of a bi-stable relay which can retain its position during power failures or energy surges. The relay automatically resets following leakage detection. Sensor voltage is 12 VDC at 50 to 60 Hz. Units are UL listed and include a 10-year comprehensive product warranty.

With more than 85 years of proven, successful experience in the global industrial marketplace, Marsh Bellofram ATC Diversified products are known for their high accuracy, reliability and dependability within a highly diverse array of demanding applications. With its strong performance characteristics, the SPM series is ideal for use in OEM; potable or wastewater sump pump; industrial or municipal pump monitoring; control package manufacturing; and general industrial leak detection applications.

2nd generation high voltage battery stack monitor

Linear Technology has announced the LTC6803, a second generation high voltage battery monitor for hybrid/electric vehicle (HEVs), electric vehicles (EVs) and other high voltage, high performance battery systems. The LTC6803 is a complete battery measuring IC that includes a 12-bit ADC, a precision voltage reference, a high voltage input multiplexer and a serial interface. Each LTC6803 can measure up to 12 individual battery cells in series. The device’s proprietary design enables multiple LTC6803s to be stacked in series without optocouplers or isolators, permitting precision voltage monitoring of every cell in long strings of series-connected batteries. The LTC6803 follows the road-proven LTC6802, introduced in September 2008 with the same functionality and pinout, plus a number of significant performance enhancements.

The maximum total measurement error of the LTC6803 is guaranteed to be less than 0.25% from -40°C to 125°C. The LTC6803 offers an extended cell measurement range from -300mV to 5V, enabling the LTC6803 to monitor a wide range of battery chemistries, as well as supercapacitors. Each cell is monitored for undervoltage and overvoltage conditions, and an associated MOSFET is available to discharge overcharged cells. Added functionality is provided by an onboard 5V regulator, temperature sensor, GPIO lines and thermistor inputs.

Erik Soule, Vice President, Signal Conditioning Products, stated, “Now over two years in the field with our proven battery stack monitor family, we are pleased to offer our customers this enhanced product, the LTC6803. Automakers and other customers worldwide have embraced Linear’s robust battery stack monitors, and we are confident that this new addition to the family will provide excellent performance for the next generation of HEVs and EVs.

“The LTC6803 addresses the latest demands of precision high performance battery stacks,” says Mike Kultgen, design manager for Linear Technology. “It ensures accurate, safe, reliable and error-free operation in harsh automotive environments.”

For long-term battery pack storage, the current consumed by the integrated BMS can potentially unbalance the cells. The LTC6803 addresses this concern with a standby mode that draws less than 12uA. Furthermore, the power input of the LTC6803 is isolated from the stack, allowing the LTC6803 to draw current from an independent source. When powering from this input, the current draw on the pack is reduced to less than 1µA.

The LTC6803 is designed to surpass the environmental, reliability and safety demands of automotive and industrial applications. The device is fully specified for operation from -40°C to 125°C. It has been engineered for ISO 26262 (ASIL) compliant systems and a full set of self-tests ensure that there are no latent fault conditions. To meet this standard, the LTC6803 includes a redundant voltage reference, extensive logic test circuitry, open wire detection capability and a watchdog timer for fail-safe designs. The LTC6803 is designed to withstand up to 75V, providing more than 20% of overvoltage margin for a full string of 12 cells. The 1MHz serial interface includes packet error checking and is designed to operate in the presence of large amounts of noise and transients.

The LTC6803 is offered in a small 8mm x 12mm surface mount device.

Measuring wheel for vehicles

Motor vehicle manufacturers are investigating ways of reducing rolling resistance and weight to improve fuel consumption of cars of the future. The new S615 6-component measuring wheel from Kistler Instruments is optimised to measure load spectra for durability, vehicle dynamics and power train investigations on the small, light vehicles currently under development.

The new measuring wheel weighs more than 800 g less that the S625 four sensor wheel, a reduction achieved by combining the three-sensor concept with extensive use of carbon fibre reinforced plastics (CFRP). The new RoaDyn S615 is designed for a maximum vertical load of 15 kN, which is more than needed for small, light vehicle applications.

The CFRP/aluminum composite wheel consists of an aluminum rim and a CFRP wheel disk. The CFRP inner part of the wheel provides the connection with the hub and the three load cells connect the rim to the inner part. To minimize local stresses all of the relevant components were optimized using finite element analysis.

The RoaDyn S615, mounted on the vehicle as a complete wheel, measures the three forces Fx, Fy, and Fz and the three torques Mx, My and Mz on the rotating wheel. Electronics built-in to the wheel convert the output from the sensors into digital format for transmission to the on-vehicle system. The system provides an analog or digital output, which is fully compatible with the rest of the Kistler RoaDyn family of products.

Engineering solutions for the Russian power industry

Delivering Smart-Grid solutions to create a comprehensive real time operations management environment

Invensys PLC met with the members of the Federation Council in Moscow to discuss about the Russian fuel and energy industry. 

During the presentation, at the Council Ulf Henriksson, CEO of Invensys PLC communicated the company’s vision for the future development of the Russian power industry.

The lack of energy regulation in Russia and the government’s directives to achieve energy efficiency and energy conservation are among the five strategic priorities for Russia’s technological development. Invensys PLC can help by combining its leading innovative technologies, global reach and practical engineering experience to help successfully manage Russia’s energy focus. Through its smart grid solutions, Invensys PLC can provide real-time communications between all sectors, particularly in Power Generation, Industrial Power and Commercial consumption.

Much needs to be done to consolidate the Russian Power industry, and Invensys PLC has already taken first steps to endure this: in addition to the meeting at the Federation Council, Invensys PLC earned support of the Non-commercial Partnership Innovations in Power Industry (NP INVEL). The Partnership with Invel unites leading companies in the power sector. Its main goal is to assist in the introduction of advanced technologies and engineering solutions at power enterprises in Russia and abroad.

Speaking on the occasion Mr. Henriksson said, "Our partnership with Invel unites two leading companies in the power sector. This allows the combination of Invensys technology with the capabilities of Invel to provide additional value to our customers".

In turn NP Invel considers the partnership with Invensys PLC as an opportunity to raise the level of Russian power industry engineering support. “Invel acts in the interests of the Partnership members and the industry as a whole. We are ready to provide informational, organisational and other necessary support to all companies that enter the Russian market to contribute advanced technologies and increase the availability of modern equipment. Request for innovations, for future technologies is impossible without familiarity with the opportunities that exist today”- said Mr. Edward Naumov, General Director for Invel.

Despite its huge potential Russia today lags behind many developed and developing countries in power asset management organisation. Delivering solutions to more than 180 countries, Invensys has acquired an excellent track record in the power industry across the world.  Implementation of their solutions can be a significant step to increase reliability and safety of the power system, and necessary for the migration of the power industry built on Smart Grid principle.

What do you do to keep your network secure?

Nowadays one only needs to read the newspaper headlines to appreciate the importance of Industrial Network Security. Almost daily an article comes out describing the threat to our critical infrastructure, from spies in our electrical grid to the looming threat of cyberwar.

Whether we talk about process control systems that run chemical plants and refineries, supervisory control and data acquisition (SCADA) systems for utilities, or factory automation systems for discrete manufacturing, the backbone of our nation’s critical infrastructure consists of these industrial networks and is dependent on their continued operation.

The second edition ofDavid J Teumim's easy-to-read book, Industrial Network Security,  introduces managers, engineers, technicians, and operators on how to keep our industrial networks secure amid rising threats from hackers, disgruntled employees, and even cyberterrorists.

How Stuxnet spreads!

Eric Byres, CTO of Byres Security Inc., Andrew Ginter, CTO of Abterra Technologies and Joel Langill, CSO of announce today the release of their joint White Paper “How Stuxnet Spreads – A Study of Infection Paths in Best Practice Systems.”  It is the first paper to detail how Stuxnet could infect a control system site protected by a high security architecture using modern, vendor-recommended best practices. The paper shows that current best practices are insufficient to block advanced threats. It then discusses what operators of control and SCADA systems need to do to protect their critical systems from future threats of this type.

• Click on image for more on Stuxnet!
Stuxnet is the first known malware to have been designed specifically to compromise a control system and sabotage an industrial process. It has been described by Symantec's forensic experts as the “most sophisticated” piece of malware they have ever seen.

The paper follows the progress of the worm as it moves through a hypothetical control system, configured according to vendor-recommended security best practices. In spite of strong security measures, the worm is able to compromise a sequence of machines, culminating in the compromise of the PLC devices which directly control the physical process.

While Stuxnet is presumed to have targeted the Siemens WinCC and PCS7 systems used at Iran’s uranium enrichment plants, its existence creates a new cyber security standard for all automation and critical infrastructure sites around the world.

Andrew Ginter remarked “The Stuxnet worm is the best-documented example of an advanced threat designed to sabotage an industrial control system. Other recent attacks have targeted control systems for industrial espionage. Control systems are now targets of advanced threats and today's best-practice defenses must be improved before they can stand against these kinds of adversaries.”

“By explaining how Stuxnet works, our paper helps security professionals understand what it takes to properly secure a state-of-the art industrial control system,” said Joel Langill. “The reality is that the majority of critical facilities are protected much less thoroughly than the hypothetical site described in our paper, and now they need to step up and protect against Stuxnet-like malware.”

“Our paper goes into great detail on Stuxnet infection pathways and highlights the difficulty of preventing infection from an advanced threat. While best practices for prevention should be implemented, control system operators should also put into practice early detection, mitigation, and containment strategies,” remarked Eric Byres. “Such strategies include putting into practice zone-based security as described in ANSI/ISA-99 Standards, paying particular attention on securing last line of defense critical systems, and understanding the unique security challenges of control systems versus IT systems.”

The paper concludes that changes to improve the cyber security of industrial control systems are urgently needed.

Level switch

New reverse assembly option for LBFS frequency-sweep level switch
The new standard version of Baumer’s LBFS level switch is made from AISI 304 or 316 stainless steel and comes with a PEEK sensor tip. In addition to this, Baumer now provides the LBFS with special G½ process connections for reverse assembly. These options broaden the field of possible applications of the LBFS. Based on the novel frequency-sweep technology, the level switch is suitable for measuring the levels of viscous or dry substances as well as liquids with a repeatability and hysteresis of ± 1 mm and a typical response time of 0.2 seconds. As the LBFS is unaffected by flow, turbulence, bubbles, foam, and suspended solids, it is particularly suitable for level detection in processes generating those.

The new G½ connection for the LBFS allows for two types of reverse assembly. The first makes it possible to mount the level switch from the inside of a tank using the included fibre gasket and a G½ nut. Fields of application include low level and leakage detection in tanks for oil or cooling fluid used in pneumatic systems or high-speed cutting (HSC) machines.

The second reverse assembly option enables the LBFS to be mounted in a simple G½ thread inside a tube to extend the length of the sensor. A fibre gasket and an M12 plug or 5-metre cable are included with the measuring device. With the tube functioning as an adjustable extension rod, the LBFS can be adjusted to changing levels. This makes it possible to use the LBFS as a float-type level switch in applications such as automatic dosing systems as well as for phase separation in the petroleum industry, hydraulic systems, and water/wastewater treatment.

Metering rubberised asphalt

Micro Motion® high temperature ELITE® Coriolis flowmeters enable accurate and reliable measurement of extremely abrasive high temperature, high viscosity fluid

BearCat Pumps of Phoenix, (AZ US) is using Micro Motion ELITE® high temperature Coriolis mass flowmeters  as part of its metering systems for rubberised asphalt, an extremely abrasive, high temperature and high viscosity fluid. The Micro Motion meters enable accurate and reliable measurement of the difficult-to-handle fluid.

“Pumping rubberised asphalt is a very challenging application that combines heat, pressure and an abrasive material,”
said Kevin T. Hill, President, BearCat Pumps. “Our experiences with other technologies have confirmed Micro Motion high temperature Coriolis meters as the best choice, as they consistently deliver the accurate readings our customers demand.”

There are two stages in the rubberised asphalt production process where material is blended and then mixed. Measurement accuracy is critical to ensure the correct blend ratios are maintained. BearCat previously used mechanical gear pumps for flow measurement, but the abrasive asphalt caused wear in the pumps, which allowed measurement accuracy to drift.

The company solved this problem by incorporating a Micro Motion high temperature Coriolis meter into its metering systems, which also include a pump and a relief or bypass valve. At start-up, heat and pressure are applied to the relief valve and sensor allowing the asphalt to circulate. The sensor of the Coriolis meter is heated using heat-jacketed surfaces that are connected to the existing heating circuit and the complete sensor is then wrapped with an insulating cover.

Developed for harsh environments, the Micro Motion meter is suitable for process temperatures up to 350ºC. Its transmitter can be mounted remotely to protect it from the heat, and the sensor can be installed anywhere with no flow conditioning or straight pipe run required. With no moving parts, the Micro Motion flowmeter requires no maintenance or repair.

To ensure accurate measurements are maintained, the Micro Motion ELITE range features in-line meter verification. This capability enables BearCat’s customers to check the sensor tubes and electronics against original factory settings while the meter is in line and the process is flowing,

These features make the Micro Motion ELITE high temperature Coriolis meters especially suited to the harsh operating environments associated with pumping asphalt. Other applications include high temperature processes such as the handling of heavy crude, bitumen, monomers, polymers, wax and cooking oils that are difficult to control and keep below a set temperature limit.
