RVDT - Rotary Position Sensor
RVDT is an abbreviation for Rotary Variable Differential Transformer, which is an angular displacement sensor. It adopts the same differential transformer principle as LVDT, i.e. the rotation of mechanical parts is transferred to the shaft of the angular displacement transducer, which drives the spoiler/core connected to it, changes the induced voltage/inductance in the coil, and outputs voltage/current signals proportional to the angle of rotation.
Single Channel - AC RVDT Rotary Position Sensor
The AC RVDT has no built-in electronics and is suitable for applications in high and low temperatures or strong shock and vibration environments. The matching signal conditioner can convert the AC signal output from the sensor to DC output.Click to viewLVDT/RVDT Signal Conditioner!

Dual channel RVDT (redundant design)
Dual-redundant RVDT adopts two identical components/channels, in case of failure of one of the channels, the other channel can still work normally, which meets the requirement of high reliability. For example, it can be applied in the control system of aircraft engine, usually need to measure the engine throttle lever angle, guide vane angle and metering valve displacement and other signals.
