Sensors

Temposonics absolute, non-contact M-Series position sensors are now approved for operation in safety-related applications. The sensors meet the requirements of Safety Integrity Level 2 (SIL2) to EN 61508 and therewith also the requirements of Performance Level d to EN 13849-1. This means the MTS position measurement systems are approved for safety functions on mobile and stationary machines. Measuring lengths from 50 mm to 2,500 mm are available.

This new sensor system allows vehicle manufacturers to accurately measure the effects of drift pull caused by steering wheel and tire alignment errors. Operators can quickly measure and record drift-pull torque and angle and determine whether the vehicle has been properly aligned after production.

ABLE is pleased to announce the availability of the new One Series Ex d, an explosion-proof electronic pressure and temperature switch for Class I, Division 1 (Zone 1) hazardous locations. Based on the One Series 2W, 4W and 8W electronic design, the One Series Ex d 2X, 4X and 8X models provide an explosion-proof enclosure based on ABLE’s popular 120 Series mechanical switches. Using the same “footprint” as the 120 Series and adding programmable digital electronics, the One Series Ex d is ideally suited for the rigors of critical areas classified as harsh and hazardous. The conduit openings, sensor port and mounting holes are in the same locations as the 120 Series for easy installation.

Endevco has announced publication of its new 2009 Product Resource. The volume is a comprehensive guide including applications, technical specifications and support programs for the company’s extensive line of products.

The VPFlowScope of VPInstruments offers direction sensitivity without the usage of extra equipment. Thanks to the patented ThermabrigdeTM sensor, measuring flow and direction is now an easy task. In the industries that use compressed air, the awareness is growing that flow measurements are key to large energy savings. In some cases however, measuring the compressed air demand is not as straightforward as it seems.

Flexible in design, Bosch Rexroth’s compact PE5 electronic pressure and vacuum switch is easy to operate and install, with three ergonomically-arranged buttons and numerous pneumatic connection options. The fully IP65-protected switch features a large, four-digit LCD display that is easy to read, and the pressure units shown can be tailored to suit the environment.

The pressure gauge MEX3 offered by Baumer’s product segment Process Instrumentation is now available in a particularly robust version for heavy duty applications. It has been developed especially for the pressure control in hydraulic parking brakes in trains. In order to protect the sensing element against shock and the impact of stones during operation, the device is mounted in an aluminium housing equipped with a polycarbonate window.

With engine efficiency under the spotlight like never before, automotive companies are exploring all avenues for improving performance. And because engines have a rotating power output, torque is the key measurement.

At this year’s Mtec 2009 exhibition (25-26 March 2009), sensor manufacturer Micro-Epsilon (UK) Ltd will be showcasing a range of unique sensor products on stand 816. The stand will include ‘live’ working demonstrations of sensor products solving real-world measurement problems.

This unique style lateral force sensor is used to evaluate the durability of passenger tires. It features an element design that is able to withstand very high extraneous loads experienced during aggressive vehicle maneuvers, while not affecting the desired tire performance measurement.
