Linear position sensor of extreme environments

Variohm EuroSensor has launched a new range of heavy duty, sealed linear position sensors for extreme operational environments. The new LWX series from Novotechnik builds upon the LWG rod actuated potentiometric design with additional sealing to IP67 protection rating and features a new patented pressure equalisation technology that prevents ‘pump effect’ pressure build up. The LWX series is available in various electrical stroke lengths up to 750mm, providing absolute measurement with resolution to 0.01mm and linearity up to 0.04%. The all-metal design includes a sturdy anodised aluminium housing with a stainless steel actuator rod supported in twin bearings with a backlash-free pivot head mounting on rod and body ends that allows up to +/- 12.5 degree free movement. The fully sealed unit is rated for 50 million movements and will suit operation in extreme environments. The LWX series environmental specifications include a vibration rating from 5 to 2000Hz at up to 20g, and shock rating to 50g for 11ms.
