MTS Sensors has increased the scope of its GB-Series of highly accurate, programmable magnetostriction-based linear position sensors so that further applications can be addressed. For these latest additions to the GB-Series (referred to as the GB-N family), the sensor rod (along with fitting flange) and the housing for the supporting electronics have a robust 1.4404 stainless steel (AISI 316L) construction, allowing their deployment in environments where there are corrosive media present. The GB-Series devices feature the company’s proprietary Temposonics magnetostrictive technology. Supporting stroke lengths from 25 mm to 3.25 m (1 in to 10.7 ft), they deliver up to 1 μm resolution, ±0.005% (full scale) repeatability and ±0.02% (full scale) linearity. These sensors are available with either analog or synchronous serial interface (SSI) output options for maximum implementation flexibility. Their operational temperature range spans from -40 to +90°C (-40 to +194°F). They have IP67-rated protection against water/dust ingress when supplied with an M12 or M16 connector. Alternatively IP68-rated protection is provided for cable outlet versions.
