Electromagnetic type angular displacement sensor detecting head. The utility model is composed of a machine core, a sleeve shell and a connecting plate. The movement adopts a short circuit ring with a rotatable angle position, and the detecting system is composed of two fixed magnetic rings. The exciting coil of the big magnetic ring is externally connected with an oscillator to provide a pulse signal, and the detecting coil of the small magnetic ring outputs the corresponding induction voltage according to the position of the short loop ring, and is amplified and output. This device has the advantages of small size, simple structure, easy manufacture, low material consumption, low cost, stable performance, high precision, and oscillator amplifier, rectifier, electromagnetic type angular displacement sensor is widely used in the field of automatic control and mechanical measurement.
