Signal conditioners help reduce cabling and maintenance costs, increase efficiency for users

Rockwell Automation have launched a new line of signal conditioners designed to help maximize the efficiency and performance of process applications by helping users isolate, convert and amplify analog signals in applications involving batch or continuous processes.

Comprised of 29 distinct products, the Allen-Bradley Bulletin 931 analog signal conditioners mark the first Rockwell Automation components specifically designed for process applications.

The Bulletin 931 analog signal conditioners isolate multiple signals on the same power source, reducing ground loop and common mode noise. By incorporating the Bulletin 931 analog signal conditioners into an existing control system, users can convert a wide range of signals from field devices into a standard 4 to 20 milliamp signal. This helps users extend the performance and functionality of legacy control systems, improves design and integration flexibility, and mitigates the need for additional I/O purchases.

The signal conditioners are designed to help reduce time and costs associated with control system installations and upgrades for a diverse range of process applications. The signal conditioners can be integrated with their PlantPAx Process Automation System, leveraging a single control platform for discrete, batch, process, safety, drives and motion control.

Users with control systems that transmit thermocouple signals over significant distances can take advantage of the Bulletin 931 analog signal conditioners to help reduce additional I/O and cabling costs. The signal conditioners convert thermocouple signals into the standard 4 to 20 milliamp signal, which can be run over long distances on standard cable with less chance of signal deterioration.

Many of the Bulletin 931 analog signal conditioners have hazardous location approvals, including ATEX and UL Class 1, Div 2 certification, helping customers meet global standards to compete internationally. In addition, transmission of data over the HART Communication Protocol is available on certain models.

Testing time for vacuum cleaner manufacturer

A company that designs and build custom test equipment for the manufacturing and research industries has developed a cost saving sub-system that allows eight dynamometer test rigs to share a single calibration unit based on a Digital TorqSense transducer from Sensor Technology Ltd.

The company, 1st Pass of Westbury (Wilts GB), started out as a regional systems integrator for National Instruments’ LabView software packages. However, it quickly realised that there was a considerable need for a wider service encompassing all aspects of test rig design and build.

Founder and Managing Director, Chris Turner, explains: “Engineers involved in either research or quality control need test rigs, but designing them is not their forte. They tend to focus only on the immediate requirements so tend towards inflexible, mono-functional designs. Six months later when new requirements emerge, they have to build another rig”.

“We saw this as a gap in the market and decided to offer the a full package whereby we would interview the engineers to establish likely future requirements, then design and build a test rig or test station that addresses all of these. This includes electrical and mechanical design, software, firmware, support systems, etc. We will also install, calibrate and maintain the rigs.”

Recently Chris was asked to visit a major West Country manufacturer to assess its needs for life testing electric motors. The company has a sizable research and development function and it was decided that no less than eight separate rigs were required. These were to be based on the well-proven concept of the test motors driving against a brake, with dynamic performance data collected from around the rig and analysed using LabView.

With the rigs’ workload expected to be high, it was sensible to go for a solid design that would last through many years of punishing duty. However, this stretched the budget so Chris applied some lateral thinking and came up with a solution.

“We needed to be able to calibrate and recalibrate the rigs on a regular basis, and we wanted the calibration process to be as simple as possible. I was able to use a TorqSense with an RS232 output for this – a sensor that can monitor the torque in a rotating shaft without actually touching it – as it opened up the potential for foolproof, robust yet sensitive calibration.”

TorqSense technology uses a radio frequency (RF) transmission link. This picks up resonant frequency signals from two piezo ceramic combs, Surface Acoustic Waves (SAW’s), fixed onto the shaft, which vary their frequency as the combs deflect under the effects of applied rotational torque. So as torque increases the combs change their resonant frequency proportionally to the change in applied torque caused by the rotating shaft.

The SAW’s function very much like as strain gauges and the RF coupling used to supply power to the SAW devices – being piezo based they need less than one milliwatt of power, is transmittable as a radio frequency and eliminates interference.”

“Initially we assumed that each rig would have its own on-board calibration unit, but I got to thinking that as they were only used at the beginning of each test run and would actually be idle the vast majority of the time. So I began to wonder about developing a demountable unit that could be shared around all the rigs.”

TorqSense’s non-contact operation and lack of flying leads make demountable installations an attractive possibility, so Chris knew he had to come up with an easy way of achieving accuracy of the transducer’s positioning. He called Sensor Technology and arranged a brainstorming session, where sliding the TorqSense unit up against end stops was identified as the best solution.

“To do this we had to find a way to move the brake away from the motor so that we had room to slip the calibrator in,” says Chris. “It was fairly obvious to mount the brake on a slide too; this was a simple solution that required little re-designing of our original concept.”

Non-contact position measurement in membrane-style packaging

The MagnetoPot is new non-contacting linear potentiometer based upon a fully sealed membrane strip and a simple magnet that together provide position feedback from 8 mm to 1200 mm in a low profile and robust design with exceptionally long life capability. Manufactured by USA based membrane sensor experts Spectra Symbol, and available exclusively in Britain from Variohm EuroSensor, the MagnetoPot is ideal for hydraulic and pneumatic position sensing and other medium precision position feedback applications such as liquid level monitoring. A rotary version is also available for compact, low profile angle sensing.

The MagnetoPot is similar in concept to a traditional membrane type potentiometer but rather than use a contacting wiper to connect the collector to the resistive element, relies upon the interaction of a non-contacting external magnet and an encapsulated magnetic or ferromagnetic strip to determine the electrical output and hence relative position. The thin IP 65 membrane has a typical membrane thickness of less than 3.5 mm - allowing the position sensor to be discretely installed with either the magnet or the membrane strip attached to the moving component.

The standard linear MagnetoPot is available in eleven travel range versions from 12.5 mm to 1000 mm with a choice of 3-pin connection options including Crimplex solder tabs, male pins and a variety of connectors. The electrical specification includes a 10 kΩ resistance output over each linear position range (5 kΩ to 500 kΩ on request) with a linearity of +/- 5%. The positioning resolution is dependent upon the exterior magnet strength and its proximity to the MagnetoPot's magnetic strip. The rotary version is currently available with a 66 mm diameter and an active centre track diameter of 46 mm.

The IP65 rating for the active area for both types of MagnetoPot allows for intense water spray and the non-contact technology effectively yields an extremely long and maintenance free working life.

German exhibition to highlight energy efficiency

The Exhibition Committee of the SENSOR+TEST and the Executive Board of the AMA Association for Sensor Technology have jointly decided to make energy efficiency the focal topic of the SENSOR+TEST trade fair this May. This will stress the special role that sensor and measuring technology plays in this future-oriented field. “Sensor and measuring technology contribute to energy efficiency in two ways: through products with a low energy consumption as well as by effectively preventing energy waste for numerous applications in practically all industries,” explains J. Achenbach, chairman of the Exhibition Committee.

Care in exploitation and handling of natural resources and the efficient use of energy are among the most important tasks for our future. This is due to the dwindling quantity of fossil fuels, high energy consumption in industrial countries and its sharp rise in developing countries, as well as the resulting impact on the environment. Besides having a low energy consumption, plants, machines, and products should not be limited in their productivity, safety, usability, or convenience. Sensor and measuring technology provides an important foundation for these objectives. For many applications, an increase in efficiency can only be implemented if exact, comprehensive, and real-time data about ambient conditions, operating states, and required parameters are available.

Due to the significance of sensor and measuring technology for energy efficiency, the SENSOR+TEST, to be held from 18 to 20 May 2010, will provide a suitable platform for this topic. Exhibitors, research institutes, and users will thus have the opportunity for a concentrated, pertinent exchange of ideas regarding this future-oriented field. A dedicated Efficiency Forum will enable exhibitors to present their novelties and solutions with posters. The forum can also be used by enterprises for low-cost table-top presentations without maintaining a stand of their own. On the first day of the fair, papers and podium discussions at the Exhibitor Forum in Hall 12 will revolve around the topic of energy efficiency. The organiser and the Exhibition Committee are convinced that many companies will make use of this opportunity to present their specific products and solutions here.

Extension & enhancement of Ethernet line extenders

Westermo Data Communications has expanded and improved its Wolverine range of industrial Ethernet line extenders with the addition of the new DDW-225 and an enhanced version of the existing DDW-120. These rugged industrial products are part of Westermo’s extensive range of Ethernet SHDSL extenders that are used to establish reliable long distance, high-speed remote connections between simple and complex Ethernet networks using any existing twisted pair copper cables.

The DDW-225 is the first Westermo line extender to include the WeOS operating system, which is already employed in Westermo’s high performance RedFox Industrial Routing Switches. WeOS provides advanced switching and routing functionality that enable the management of complex industrial networks.

The enhanced DDW-120 is aimed at simple point-to-point applications, or as a start or termination unit, together with any of the DDW-220/221/222/225 products, in daisy-chain applications. The latest version of the extender enables data transmission rates as high as 15.3 Mbit/s in both directions, and transmission distances of over 10km, depending on cable quality. This increased data transmission rate will help meet the ever increasing demands for bandwidth from applications such as transmitting high definition video from remote sites.

The new product supports two SHDSL interfaces and has a built in four port managed Ethernet switch, enabling users to build complete Ethernet networks with daisy chains and ring topologies. Suitable for use in extremely harsh industrial environments, the device offers a data transfer rate of 5.7 Mbit/s in both directions, and transmission distances of up to 15km. This makes it especially useful for applications such as railway trackside, tunnels, highways, harbours, power stations and extended industrial plants.

The DDW-225 also includes the company's unique FRNT (Fast Recovery of Network Topology) technology, the fastest protocol on the market to re-configure a network in the event of any failure of a link or hardware, which provides support for redundant rings. The DDW-225 can also support multiple rings, with a FRNT ring running from the SHDSL interface and a RSTP ring from the switch port. Device functionality, including VLAN, Static Routing, Layer 3 switching, IGMP Snooping Firewall, SNMP V3 and VPN support all help improve bandwidth support and network security.

The DDW-120 is designed to be transparent for multicast addressing, is suitable for VLAN networks, allows VPN (Virtual Private Network) pass-through for IPSec (Internet Protocol Security) and can be used with protocols like Modbus®/ TCP and PROFINET® I/O. The DDW-120 is very simple to install, with no software configuration required. When long or poor cabling is used the settings can be adjusted via DIP-switches for optimised performance. The unit is also supplied with an advanced diagnostic utility that allows the installer to analyse the quality of the line and the connection status.

As with other products in the Wolverine series, both models are suitable for tough industrial environments. The rugged units can operate in a wide temperature range and total galvanic isolation and transient protection are standard for all interfaces. The line interface is also equipped with extensive protection against over-voltages and transients.

After Buncefield

Instruments chosen for new multi-agency air quality unit
Pic: Royal Chiltern Air Support Unit

Environmental instrumentation company Quantitech has been awarded a contract worth in excess of £1million to provide advanced air sampling and analysis equipment to the multi-agency air quality cell that has been established following the recommendations of the Major Incident Investigation Board for the Buncefield incident.

Quantitech has supplied 18 sets of instrumentation including their advanced portable Gasmet FTIR multi-gas analysers in addition to TCR Tecora high volume Echo and low volume Delta air sampling equipment.

The company has also been responsible for the provision of a thorough training programme covering instrument operation, maintenance, calibration and service.

The project was created to develop an air monitoring and modelling capability for major pollution incidents affecting England and Wales. Participants include the Environment Agency, the Health Protection Agency, Public Health Wales, the Met Office, the Health and Safety Laboratory, the Food Standards Agency and Local Authorities.

Quantitech's Dr Andrew Hobson has been responsible for providing initial training on the instruments. He says, "We are delighted that the Gasmet DX4030 portable FTIR gas analyser has been chosen for this project because it was developed for applications in which almost any gas might need to be identified.

"The FTIR analyser is located in a backpack and effectively provides laboratory grade analysis in a field instrument. A Bluetooth connection to a handheld PDA provides simultaneous measurements for up to 25 compounds and the collection of a complete sample spectrum means that over 250 compounds can be analysed."

Summarising progress to-date, the Environment Agency's Gillian Hickey, service manager for monitoring in the Air Quality in Major Incidents project, says, "Over the last 6 months we have responded to a number of chemical air pollution incidents with enhanced interim arrangements.

"Our experience and the lessons learned at these incidents, which have included fires at tyre recycling sites, a waste management transfer site, an electrical recycling site and a publishing warehouse, are proving invaluable in the development of our monitoring and modelling capability, which will be fully established in April 2010."

Portable monitoring equipment is vital to the success of the project because of the rapid response times that have been established by the project. The Emergency Services will notify the Environment Agency within 30 minutes of a major pollution incident and the Environment Agency will then convene the Air Quality Cell (AQC).

CHEMET air modelling information from the Met Office will be available within 20 minutes with more detailed modelling provided later.

The Environment Agency will mobilise monitoring teams from one or more of eight locations and monitoring data will be provided to the AQC within 2 to 6 hours of the incident.

The Buncefield explosion near Hemel Hempstead in December 2005 raised a number of environmental issues and Quantitech's Dr Hobson says he is "delighted to have played a role in one of the very positive outcomes to have been initiated by this major incident," adding, "This is a very important contract for Quantitech and one that has enabled us to exercise the core capabilities of our company. Namely, leading edge technology in combination with the highest levels of technical support."

Condensation monitor

Avoid forming of irritating droplets and wetness

Cooling ceilings, critical areas in HVAC and technical installations, which are operating close to the dewpoint temperature, need an early alarm system against the forming of moisture, because of the potential danger of condensation. The new condensation monitor EE46 from E+E Elektronik is specially designed for such applications and can be installed in a few seconds on pipelines, walls, and ceilings.

The early detection of “danger of condensation” and as a result the immediate start of counter measures renders this product as very significant.

A special coating protects the sensor and electronics against dirt and dust – a guarantee for a longstanding, stable and above all maintenance free operation.

The fast response, high accurate E+E humidity sensor is exposed to the temperature of the surface of the object by means of a thermal conducting foil. Therefore, the humidity sensor measures the same relative humidity as is present at the surface of the object to be monitored.

If the preset set point of 90 %RH is exceeded the EE46 switches a potential free contact and provides a signal enabling to take early counter measures, e.g. to increase the temperature of the water in the pipe, to decrease the cooling power or to turn on the heat. In addition, a LED on the enclosure indicates the actual status.

The condensation monitor of the Series EE46 is designed to be powered by 24 V ac/dc.

These products are marketed in Ireland by Instrument Technology.

Safety & security

Symposium for Big Easy!

The International Society of Automation has announced that the 2010 Industrial Automation Safety and Security Symposium, sponsored by the ISA Safety Division, will take place 28-29 April 2010 in the French Quarter of New Orleans (LA US). This year’s symposium will focus on threats—including cyber security threats—to industrial environments and the steps engineers must consider when designing and optimizing industrial processes and Safety Instrumented Systems (SIS).

ISA training courses include Safety Instrumented Systems (SIS) and the ANSI/ISA-84 standard, and industrial automation security and the ANSI/ISA-99 standard.

Symposium presentations will provide practical and useful guidance for designing industrial processes, selecting SIS, and protecting these systems against cyber threats and dangerous failures.

The day will include three tracks—Alarm Management, SIS, and Cyber Security—and will end with a safety and security panel discussion. The event will provide an in-depth look at today's safety and security technologies and procedures. It is intended to create a forum where paper presentations and panel discussions transfer information from the leaders and experts on safety and control to industry professionals. A full program will include expert-led sessions, training, social functions, and more.

Linear accelerometers

Provide precision single, biaxial or triaxial measurement capabilities

Sherborne Sensors has introduced the A545 series, a range of single, biaxial and triaxial solid state linear accelerometers, designed to measure acceleration and deceleration within demanding environments, and within the same, compact package size.

Available in ranges from ±2 to ±500g, A545 series accelerometers feature an advanced MEMS sensor, incorporating air damping. Unlike fluid-damped devices, air damping is essentially independent of temperature, which enables the transducer to reliably perform over a wide temperature range. Sensors are fully compensated for temperature effects on both sensitivity and zero, and incorporate positive mechanical stops. Housed within a robust, lightweight, (less than 40 gm), durable light alloy package with solder pin connectors, the A545 series confers excellent shock resistance, and provides reliable over-ranging protection. The A545 series is designed to operate from an unregulated DC power source and have useable frequency responses from DC to several kHz.

Typical applications for this series include data acquisition systems, crash testing, fatigue life monitoring and prediction, low-frequency vibration analysis, and structural surveying. Custom designed units can also be manufactured and tested to conform to specific requirements. All A545 series accelerometers are 100% tested and calibrated at the factory prior to shipment, and are accompanied by a two-year comprehensive warranty. These accelerometers are also part of the new Sherborne Sensors Guaranteed On-Time Delivery program.

They have the added benefits of ISO9001: 2000 certified manufacturing, extensive applications engineering support, global technical sales presence, repair, refurbishment and calibration services, stocking programs, and continuous product improvements.

4.5 million downloads

Data Portal has extensive collection of device and component data

In just one year after its much anticipated launch, the EPLAN Data Portal has had a tremendous effect on engineering - 4.5 million downloads speak for themselves. This innovative web-based portal delivers around 100,000 items of the latest tested and certified component and device data from numerous leading component manufacturers, thereby giving users an extra productivity boost.

In addition to perfect software support, engineers need suitable component data that can be imported directly into a project. With its extensive collection of device and component data from renowned manufacturers, this Data Portal ensures seamless engineering at maximum speed. In no time at all, a desired component can be found by using a keyword, manufacturer’s name, product group or catalogue view in the direct search function. The time-consuming act of browsing through catalogues and manually transferring information are a thing of the past. Data is entered directly in a project from the EPLAN Data Portal - with all the convenient functions of a web-based solution.

Manufacturers currently participating in EPLAN Data Portal are ABB, B&R, Bachmann Electronic, Eaton/Moeller, HARTING, Helukabel, Igus, Lapp Kabel, Martens Elektronik, Michael Riedel Transformatoren, Pepperl+Fuchs, Phoenix Contact, Pilz, Rittal, Rockwell Automation/Allen Bradley, Schneider Electric, SEW, Siemens, Vishay ESTA, WAGO, Weidmüller.

Lifting & weighing

A Range of shackle load cells for harsh Environments

LCM Systems has introduced an innovative range of shackle load cells designed specifically for lifting and weighing applications in harsh or rugged environments. Ideal for use in applications such as under-hook hoist and crane weighing, cable tension monitoring and crane load safety monitoring, the sensors are available in either cabled or wireless telemetry versions.

Ever mindful of customers’ needs and preferences, they can provide the cabled versions with Crosby shackles as standard or as an option with Greenpin shackles. Safety is paramount for the demanding applications in which these shackle load cells are used and the use of high-quality shackles is essential to comply with safety standards and regulations as well as to maintain integrity.

The SHK-D cabled, shackle load cells use the Crosby G2150 and are available in a range from 1 tonne to 35 tonne, while the SHK-B cabled series has a rated load up to 400 tonne, using either the Crosby G2130 or G2140. All shackle pins are forged from high tensile carbon steel and proof loaded to 150% of the normal rated load. The standard product is sealed to IP66 to protect against harsh weather conditions. All load cells in the series are easy to install and can be supplied with a range of instrumentation for a complete load monitoring system.

For engineers wanting a wireless, telemetry option, the TELSHACK range uses integral wireless telemetry electronics operating on the 2.4GHz license-free frequency. Two ranges are offered: TELSHACK-D can be used from 12 tonne to 35 tonne, while the TELSHACK-B can be used for applications up to 400 tonne. Both ranges can be supplied with either Crosby or Greenpinshackles and experienced design engineers at the company can provide expert advice on the correct shackle for each application.

One of the main features of the TELSHACK ranges is that the housing is supplied with a built-in rechargeable battery. This means that they can be removed from the shackle for charging, while the shackle itself remains in place. A handheld battery powered display is supplied as standard with the option of a single display that can monitor up to 12 shackles when the load cells are used in a multi-shackle configuration, either individually or for summation/balancing applications.

LCM Systems’ standard range of shackle load cells can provide an ideal and safe solution for many applications. However, for more complex requirements their Technical Department will work closely with application engineers to provide customised and workable systems for even the most complex applications.

Profibus again!

User Conference 2010

PROFIBUS UK tells us that the 7th annual PROFIBUS and PROFINET User Conference will be held from 29-30 June 2010 at Stratford-on-Avon in Warwickshire. Following the successful theme established as a result of six years of positive delegate feedback, this user focused event will feature a comprehensive, multi-stream educational programme that will lead new users through both PROFIBUS and PROFINET, from the basic technology through to its use and application experience in real world industrial and process applications.

The two-day Conference offers a selection of application-oriented technical presentations and hands-on workshop sessions presented by experienced users, technology experts and systems builders. These are people who are training practical PROFIBUS and PROFINET engineers and installers, who are designing and building new systems or system expansions using the technology, or who have installed such systems in their plant, and wish to relate their experience.

The conference will assist companies that own, operate, design, build or maintain manufacturing facilities and process plant, in making the transition from conventional to fieldbus systems as easy (and jargon free) as possible, by covering the latest developments in PROFIBUS, PROFINET and PROFIsafe technology for factory and process automation.

The carefully organised conference and workshop schedule means that you can attend hands-on sessions without having to miss a relevant presentation. The event is supported by a free of charge exhibition, with interactive displays and technology demonstrations from the UK's PROFIBUS Competence Centre, and leading product vendors, trainers, consultants and systems integrators.

To ensure that no-one goes away with unanswered questions, PROFIBUS gives pre-registered delegates the chance to pose their questions in advance of the Conference. In addition, what subject areas are the most important for you in such a conference? While we're still in the process of putting the programme together, there's still a chance to influence the content! This year the schedule has added topics such as energy efficiency, and water saving, but what else would you wish to see covered – submit your suggestions with the registration form, available via the website.
