Positek Limited expand range – new pressure transducers, temperature probes, displays and cable extension transducers

Pressure sensors, temperature probes and cable extension transducers significantly expand Positek Limited product range

Positek Limited has increased its comprehensive range of precision sensors with new pressure transducer and temperature probe product lines along with dedicated instrumentation displays. In addition, a broad range of cable extension transducers will supplement the Gloucester based displacement transducer manufacturer’s extensive portfolio of linear, rotary, tilt and intrinsically safe position sensors. The increased range follows Positek’s acquisition by The Variohm Group earlier this year that promised and has already begun to deliver in-depth partnerships between its members with shared complementary products and technical expertise.

The new pressure transducer and temperature probe lines now supported by Positek Limited are designed and manufactured by Group partner Variohm EuroSensor. EPT series pressure transducers cover a very wide application and market areas for gas and liquid pressure measurement from fluid power to HVACR and from chemical & industrial plant to medical instruments. Across the EPT range, gauge, absolute and differential pressure measurement from a few millibars to several thousand bars is taken care of with 12 product series’ offering an extensive selection of pressure port interfaces, electrical connection, output characteristics and environmental ratings. These pressure transducers typically utilise piezo resistive sensing element technologies coupled with the latest ASIC circuitry. They are compatible with stainless steel wetted parts and other materials from plastics and brass for low cost solutions at low pressure levels to materials with improved chemical resistance against aggressive media or extremely high temperatures. Combined pressure and temperature measurement of up to 1000 bar and temperature range between -50 to +150°C is also possible with Variohm’s EuroSensor’s EPTTE series transducers.

Positek’s new ETP series temperature probes utilise Variohm EuroSensor’s well developed overmoulding technology as cost-effective measurement solutions that integrate proprietary NTC, PT100/1000 and other temperature sensor types into convenient measurement packages. This includes encapsulated temperature probes in pipe clamps, ring terminals, hexagonal bolts, PTFE and brass cylinders, plastic straps and other components that can be directly assembled directly into a machine or instrument application. Saving installation time and cost, the IP67 rated probes are used extensively for general Instrumentation, medical & communication equipment, machine integration, HVAC and many other precision temperature measurement tasks. With a wide standard range the ETP series typically suits precision temperature measurement between -40 and +125°C for NTC types and -40 to +250°C for PT100/1000 sensing elements. Custom modified versions are available for alternative temperature ranges and modified mechanical interfacing – for instance with alternative bolt thread dimensions.

Complementary displays are also now available from Positek. Manufactured by Orbit Merret and with compatibility for all of the various output types available for pressure and temperature measurement, users can select the appropriate read-out characteristics in panel mount and din-rail mount designs.

Cable extension transducers or draw wire sensors provide an alternative technique for measuring linear displacement and offer a logical product expansion Positek’s comprehensive range of highly specialised non-contacting linear and rotary voltage displacement sensor technologies. Manufactured by TE Connectivity – a Variohm Group distribution partner – the extensive range includes miniature designs for instrument type measurement tasks up to highly durable IP68 rated units for harsh environment use. Measurement techniques include potentiometer and incremental encoders with industrial standard current and voltage output as well as digital output options such as CANopen or RS232. With measurement ranges from 60 mm to several metres, accuracy from 0.04% to 0.18 % FS, and repeatability to 0.02%, this technology suits straightforward medium precision linear measurement tasks where a proven reliability in automation, structural engineering, medical, and test and measurement applications is essential.
