High/Low Temperature Rotary Transformer:

Rotary transformer is a kind of electromagnetic sensor, also known as synchronous decomposition device, used to measure the angular displacement and angular velocity of the rotating object, composed of stator and rotor. 

The stator winding is used as the original side of the transformer and accepts the excitation voltage, and the excitation frequency is usually 2K~20K. The rotor winding serves as the auxiliary edge of the transformer, and the induced voltage is obtained by electronic coupling. 

The voltage amplitude of the output winding of the rotary transformer is a sine and cosine function of the rotor corner.
