Transducers and Position Sensors

Transducers have been employed on both military and commercial aircraft to provide position feedback information of flight control surfaces to the flight computers, autopilots and cockpit displays.听Our modules are configured with synchro transmitters, rotary variable differential transformers (RVDT), splined input shaft, anti-backlash spur gearing, electrical receptacles and explosion flame arrestor vents.
