COMPENSATORY ACCELEROMETER Russian patent published in 2020 - IPC G01P15/13 

FIELD: measuring equipment.

SUBSTANCE: essence of invention consists in fact that compensation accelerometer additionally contains local negative feedback from amplifier output, through high-pass filter, to one of the torque sensor inputs, relay element shunted by delay link, from integrator output to comparator input, as well as a flip-flop from the comparison circuit output to the electronic switch input, the output of which is connected to one of the torque sensor inputs, output of the reversible binary counter is the digital output of the compensation accelerometer.

EFFECT: high measurement accuracy, broader pass band.
