ACCELEROMETER Russian patent published in 2015 - IPC G01P15/13 

FIELD: instrumentation.

SUBSTANCE: device comprises a sensitive element (1), a position sensor (2), the outlet of which is connected to an input of an amplifier (4) with stable amplification ratio, a magnetoelectric power converter (15), connected into negative feedback. At the same time it includes analogue, integrating and discrete negative feedbacks. The analogue negative feedback is implemented at the outlet of the position sensor (2) to one of the inlets of the magnetoelectric power converter (15) via the following components serially connected along information inlets: an AC amplifier (4), the first logical element (5), an EXCLUSIVE OR circuit (8), a filter (9), the first converter (10) of voltage-current and a summator (11). The integrating negative feedback is implemented from the outlet of the EXCLUSIVE OR circuit (8) to the input of the magnetoelectric power converter (15) via the following components that are serially connected by information inputs: the first integrator (12), the second converter (13) of voltage-current and the summator (11). The discrete negative feedback is implemented from the outlet of the EXCLUSIVE OR circuit (8) to the input of the magnetoelectric power converter (15) via the following components that are serially connected by information inputs: a trigger (14) and the summator (11). Besides, a reference voltage generator (3) is connected both with the position sensor (2) and with a phase shifter (6). The outlet of the phase shifter (6) is connected to one of inlets of the EXCLUSIVE OR circuit (8) via the second logical element (7). One of outlets of the trigger (14) is connected to the inlet of a reversible binary counter (16), the outlet of which is a discrete outlet of the accelerometer.

EFFECT: expansion of pass band and increased accuracy of acceleration measurements.
