Variohm EuroSensor's VLP and ELP linear potentiometer position sensors get performance facelift
18/04/2012 Variohm EuroSensor Ltd
Towcester - UK - April 2012: Variohm EuroSensor has been manufacturing its own VLP and ELP range of linear potentiometer position transducers within the Variohm Holdings Group for several years and has recently introduced new dual-lip sealing design improvements for extended reliability and longer life in harsh environments.This well proven sensor range, available from 12.5 mm up to 300 mm stroke lengths in 25 mm increments with custom lengths available on request, is available in a choice of 15 mm or 9.5 mm diameter cylindrical housings. With self-aligning spherical bearing mounts and optional quick release mechanisms, the range provides up to +/- 0.05% independent linearity and positioning repeatability to 0.01 mm.
The improved O-ring and felt shaft sealing arrangement provides a choice of IP65 or IP67 protection in a compact design that keeps the overall sensor length shorter than competitive devices from other manufacturers.
Central to the performance, operational life and reliability of the VLP and ELP series is the Novotechnik patented wiper system which offers protection in applications involving high vibration. The sensing technology combines a conductive plastic resistance element built up using several layers of specialised printed inks with multi-fingered precious metal wipers in a unique elastomer damped mechanism that maintains complete, smooth and uninterrupted contact with very low electrical noise, even under the most arduous physical and environmental conditions.
These sensors are well proven in autosport applications where shock and vibration conditions far exceed those normally seen in industry. High temperature range versions are also available for up to +150 ºC continuous with short term ratings to +175 ºC. Life expectancy across the range is better than 25 million cycles.
Variohm manufactures a comprehensive standard range of VLP and ELP linear potentiometric sensors, available from stock and on fast delivery times. Customised designs with alternative stroke lengths, different mounting arrangements, modified electrical characteristics, or other customer requested changes are also available.
