CAPACITIVE MOTION SENSOR Russian patent published in 2021 - IPC G01P15/08 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measuring technology and can be used to measure linear or angular displacements. The capacitive displacement sensor contains a bridge circuit, in two arms of which capacitors are included with the possibility of changing the capacitance depending on the movement of the movable plates, while the design parameters of the capacitors and the circular frequency of the sinusoidal voltage generator are connected by a functional relationship that determines the setting for maximum sensitivity to movement , where S, h₀ is the area of the plates (collectors) of the capacitors and the distance between them in the absence of movement, the resistance of the balanced resistors, the relative permittivity of the medium in which the device operates, and the dielectric constant.

EFFECT: increased sensitivity of the capacitive displacement sensor.
