COMPENSATION-TYPE ACCELEROMETER Russian patent published in 2015 - IPC G01P15/00 

FIELD: measurement equipment.

SUBSTANCE: compensation-type accelerometer is intended to be used as a sensitive element in stabilisation and navigation systems. The invention can be used in measurement instruments of mechanical values of a compensation type. A compensation-type accelerometer includes a sensitive element, an angle transmitter, a phase detector of negative feedback, an integrating amplifier, a reference voltage generator, the outputs of which are connected to inputs of the angle transmitter and the phase detector of negative feedback, which are in series connected via information inputs from the comparator output to the input of the comparison circuit, a level transducer, 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, a current generator connected to the input of an electronic switch, an auxiliary frequency generator connected to the comparator inputs, a pair of waiting synchronous generators, an adding binary counter and a reversible binary counter, and an integrator introduced from outputs of the phase detector of negative feedback to one of the inputs of a torque sensor. To the comparator input there introduced in series via information inputs is the first differentiating filter and the adder, and to the input of the threshold element of the second differentiating filter from the output of the comparison circuit. One of the outputs of the phase detector of negative feedback is connected to one of the adder inputs, and the output from the reversible binary counter is a digital output of the compensation-type accelerometer.

EFFECT: introduction to a compensation-type accelerometer of two negative feedbacks, one of which includes an integrator, and the other one includes differentiating filters; it allows creating a device operating in a self-oscillating mode, with astatism as to deviation and with an enlarged band pass and considerable quick action.
