VOLUMETRIC MECHANICAL VIBRATION SENSOR Russian patent published in 2019 - IPC G01P15/09 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment, in particular to sensors for measuring parameters of mechanical vibrations, and can be used to measure parameters of mechanical vibrations of various objects in machine building. Volumetric sensor of mechanical vibrations includes base, piezoelectric elements rigidly fixed on the base, bushing with fixtures, in which on the thread to the base a bushing with fixtures is fixed, on which vertices of equilateral triangle or square are rigidly fixed guide cylinders, in which are inserted movable bushings with balls installed on upper edge, fixed by nut, resting on support spring, lower end of which is conjugated with piezoelectric element.

EFFECT: expansion of measured displacement parameters (linear and angular), speed, acceleration, vibration (frequency, period, amplitude), which enables to obtain more accurate measurements.
