COMPENSATION ACCELEROMETER Russian patent published in 2014 - IPC G01P15/13 

FIELD: measurement equipment.

SUBSTANCE: compensation accelerometer comprises a sensitive element, an angle sensor, an amplifier, a phase detector of negative feedback, an integrating negative feedback from the outlet of the comparator to the inlet of the torque sensor via serially connected comparator, level converter, a pair of waiting synchronous generators, reversible binary counter, comparison circuit, trigger, electronic key, connected by information inlets. Besides, there is a filter from the outlet of the comparison circuit to the inlet of the trigger and an analog-digital converter, a threshold element and an integrator from the outlet of the phase detector of negative feedback to the inlet of the comparator. The outlet of the reversible binary counter is a digital outlet of the compensation accelerometer.

EFFECT: introduction of a filter, an integrator, an analog-digital converter, a threshold element and an integrating negative feedback into a compensation accelerometer makes it possible to stabilise parameters of the compensation accelerometer, to increase accuracy of measurement and to expand the pass band due to realisation of an astable mode in the device.
