New VXP linear position sensor has extended environmental specification and a thoroughly proven design for demanding industrial measurement

Variohm EuroSensor has introduced 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 thoroughly 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 + 150 ºC with a short term ceiling of 175ºC. 

The new VXP linear position sensor is an absolute position measuring device available for stroke lengths from 25 to 290 mm in 9 standard models. The impressive sensor specification includes a typical independent linearity of +/- 0.1%, a positioning repeatability to 0.01 mm, shock rating of 50 g for 10 miliseconds, and a maximum speed up to 10 metres per second. Working life is better than 25 million cycles.  Its 15 mm 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 remains the smallest available in the industry – perfect 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 a unique elastomer damped mechanism. This sensor element technology maintains a constant, smooth and uninterrupted contact even under the demanding shock and vibration conditions.
