MULTICOMPONENT DISPLACEMENT SENSOR Russian patent published in 2013 - IPC G01L1/00 

FIELD: measurement equipment.

SUBSTANCE: multicomponent displacement sensor includes a housing and a sensitive element with piezoelectric detectors. Force-receiving element is made of two longitudinally connected elastic bars, the end faces of which are connected by means of a ball hinge, on which a force transfer element is arranged, which is made in the form of a ball bearing installed with its inner race on force-receiving element in maximum deflection zone; sensitive element is made in the form of a deformed outer race of the above bearing, which is located concentrically to inner race. On internal surface of deformed race there are openings for arrangement of piezoelectric elements, and bearing cage is fixed against annular displacement relative to support ring so that each ball of the bearing contacts the working surface of piezoelectric element so that centres of balls coincide with direction of radial movements of sensitive element of the sensor.

EFFECT: enlarging functional capabilities of the device.
