DEVICE FOR MEASURING VIBRATION ACCELERATIONS OCCURRING IN ELECTRICAL INSTALLATIONS Russian patent published in 2024 - IPC G01P15/09 G01P1/02 

FIELD: measurement.

SUBSTANCE: invention relates to instrumentation, namely to devices for electrical measurements of non-electrical quantities and can be used to measure vibration accelerations of industrial facilities at high temperature and high intensity of alternating magnetic field. Device for measuring vibration accelerations occurring in electrical installations comprises a base of a housing of a sensitive element with a piezoelectric plate with electrodes, an inertial mass, sensitive element housing cover, shielded cable and electronic conversion unit. Inertial mass is made in the form of a package of metal plates with high specific electric resistance and magnetic permeability connected by high-temperature glue.

EFFECT: reduced heating of the sensitive element of the device by Foucault currents and magnetization reversal due to the exclusion of massive metal assembly units from the device and the implementation of the inertial mass in the form of a package of glued together metal sheets with high specific electrical resistance, higher thermal stability of device parameters.
