Variohm EuroSensor is introducing a new potentiometric linear position sensor featuring IP67 sealing, improved reliability and increased operational temperature capability. Well suited to challenging applications in industrial measurement, the VXP series is based upon the field-proven VLPM motorsports potentiometric sensor that Variohm have manufactured for several years along with its industrial application-oriented sister version, the VLP. Design improvements across both versions include a new dual-lip sealing arrangement, and improved materials on the VXP that have enabled an IP67 rating and a higher temperature capability of -40 to + 150degC with a short-term ceiling of 175degC.
Variohm’s new VXP linear position sensor is an absolute position measuring device available for stroke lengths from 25 to 290mm in nine standard models. The sensor specification includes a typical independent linearity of +/- 0.1 per cent, a positioning repeatability to 0.01mm, shock rating of 50 g for 10 miliseconds, and a maximum speed up to 10m per second. Working life is better than 25 million cycles. Its 15mm square anodised aluminium housing features self-aligning spherical bearing mounts for straightforward installation. Through the complete range the ratio of the extended full measuring length to the body length is claimed to be the smallest available in the industry – useful for applications with restricted mounting space.
The conductive plastic resistance element technology utilised in the VXP and VLP series combines a resistance element built up by a specialised and patented technique using multiple layers of printed inks that combine with multi-fingered precious metal wipers secured in an elastomer-damped mechanism. This sensor element technology maintains a constant, smooth and uninterrupted contact even under the demanding shock and vibration conditions.
