Abstract

PURPOSE: To increase a linear area of the capacity variation characteristic, by constituting an auxiliary differential capacitor by providing an auxiliary fixed electrode in addition to a fixed electrode of a capacitor type microdisplacement detector, and correcting the capacity variation characteristic of the differential capacitor.
CONSTITUTION: Auxiliary fixed electrodes E11', E12' of small dimensions (small capacity) are provided on the adjacent position in the same plane as the main fixed electrodes E11, E12 placing a moving electrode EV of the capacitor type microdisplacement detector between them. The auxiliary capacitor CK is formed in parallel with the main capacitor CL, the capacity variation characteristic CL is corrected by the capacity variation of CK, and a linear area of the composite capacity variation characteristic is increased remarkably.
