Abstract
PURPOSE: To simplify the circuit constitution of the entire part of a displacement converter by using a capacity type displacement detector provided with stationary electrodes only on one side of a moving electrode which is moved by displacement.
CONSTITUTION: AC voltage is applied from an oscillator 20 to a displacement detector 18 consisting of the 1st, 2nd stationary electrodes provided in opposition to one side of a moving electrode moved by displacement and the moving electrode. The electric current flowing to the 1st variable capacity part C1, 2nd variable capacity part C2 of the displacement detector 18 is rectified at D1, D2, and is applied to a control means 21 which so controls the amplitude of the output of the oscillator 20 that the detection signal having been rectified always assume a fixed value. The voltage e1 corresponding to the displacement generated in a resistor R1 is made to the current signal I0 by a voltage-current converting circuit 27, and is sent out to a receiver 29.
