DEVICE FOR MEASURING THE TECHNICAL CHARACTERISTICS OF MECHANOELECTRIC TRANSDUCERS WITH A CAPACITIVE OUTPUT AND A METHOD FOR MEASURING THE CONVERSION COEFFICIENT BY CHARGE (OPTIONS) Russian patent published in 2023 - IPC G01R29/22 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a non-contact position sensor in the system that connects the test sample with the control unit and the electric current to electrodynamic converter (EDC), including the magnetic system.

EFFECT: invention makes it possible to ensure the accuracy of the placement of the coil winding in the gap between the pole pieces of the magnetic system, which significantly reduces the effect of the nonlinearity of current conversion in force and ensures no force losses on the branch to the suspension and, accordingly, high accuracy of the transfer of the generated forces to the test sample, which leads to the possibility of carrying out measurements without comparing the latter with the reference values of the test sample.
