Abstract
PURPOSE: To arrange so that an output proportional to a displacement under a constitution not symmetrical may be obtained and besides be increased, by providing a constitution such that a differential signal between a variable impedance element and a fixed impedance element is constant through control.
CONSTITUTION: A fixed capacity element C1 formed between a metal ring 7 and a fixed electrode 11 is provided between the terminals 12W13 of a displacement detector 18. In addition, a mobile electrode 5 and a variable capacity element C2 formed between the metal ring 7 and a fixed electrode 10 are provided between terminals 12W14. Between the terminal 12 and a common potential point 19, an output terminal for an oscillator 20 is connected as a power supply. Under this design, an electric signal corresponding to the differential between the capacities of the fixed capacity element C1 and the variable capacity element C2 is detected. Then the amplitude of an output from the oscillator is controlled by control means 21 so that a detection signal may always be a constant value.
