PENDULUM ACCELEROMETER SENSOR WITH CONDITIONED CAPACITANCE DETECTION Russian patent published in 2024 - IPC G01P15/13 

FIELD: physics.

SUBSTANCE: group of inventions relates to a closed-loop pendulum accelerometer sensor. Accelerometric sensor control unit is configured to supply, during each calibration period, a first detection signal to one of said fixed electrodes, selected in accordance with the logic level of the control signal, and the second detection signal to another fixed electrode, wherein control signal (u) is supplied to electrode, to which second detection signal is supplied.

EFFECT: reduced power consumption of the sensor, elimination of scale factor error.
