RVDT position sensors

The RVDT is an angular position sensor that produces an output voltage proportional to the rotary displacement of an operating shaft. The sensor is constructed from stainless steel and has an operating shaft set within 'twin' ball-race shaft bearings for precision and integrity. Active Sensors RVDT's are manufactured to quality standards required for high performance, high cyclic control and measurement systems including flight control actuator or servo valve systems.

Precision coil winding techniques provide the necessary environmental protection required to avoid dielectric breakdown and produce electrical output stability under vibration, acceleration, mechanical and thermal shock. The sensors are lightweight and robust with a measurement angle up to +/- 80° in single and duplex designs. Environmental testing available: RTCA DO160, EUROCAE/ED-14, MIL-STD-810 -Altitude, Temperature, Humidity, Icing, Freezing rain, Shock, Vibration, Sand and dust, Fluid susceptibility and Fungus resistance.
