Abstract

PURPOSE: To obtain the output proportional linearly to displacement amounts by operating the ratio of the output signals of an impedance element which responds to displacement amounts and an impedance element which does not.
CONSTITUTION: The output of an oscillation circuit 27 is supplied to a capacitor C24 of which capacity changes according to physical displacements and a capacitor C25 which does not respond to the displacements. The signals corresponding to the respective impedance values of the respective C24, C25 are detected by way of diodes 28, 29. The ratio of the respective detection signals is obtained by performing division in an arithmetic circuit 39. As a result of this, the output proportional linearly to the displacement amounts may be obtained.
