COMPENSATION-TYPE ACCELEROMETER Russian patent published in 2015 - IPC G01P15/13 

FIELD: measurement equipment.

SUBSTANCE: compensation-type accelerometer includes a sensitive element, an angle sensor, a phase detector of negative feedback and an integrating amplifier. A reference voltage generator is connected both to the input of the angle sensor and to the input of the phase detector of negative feedback. The comparator output is connected in series via information inputs to the torque sensor input through a level converter, a pair of waiting synchronous generators, a reversible binary counter, an adding binary counter, the output of which is connected to one of the inputs of the comparison circuit, a threshold element, an electronic key, a current generator connected to the input of the electronic key. An auxiliary frequency generator is connected to inputs of the comparator, the pair of waiting synchronous generators, the adding binary counter and the reversible binary counter. One of the outputs of the phase detector of negative feedback is connected to the input of the torque sensor through a filter. To the comparator input there introduced is a stabilising circuit containing two outlines, the input of which is connected to the output of the phase detector of negative feedback. The output of the reversible binary counter is a digital output of the compensation-type accelerometer.

EFFECT: possible measurement of accelerations; a compensation-type accelerometer operates in an autooscillation mode, with astatism and with enlarged band-pass and considerable quick action.
