Abstract
A capacitance type displacement conversion device is provided in which a physical displacement resulted from a change of a physical value such as pressure or tension is converted into an electrical signal. The device is comprised of a capacitance sensor and an improved circuitry whereby conversion characteristics are linear and free from erroneous measurements caused by distributed capacitances and other circuit elements related thereto. The type of the sensor may be either a single capacitance or a differential capacitance type.
