COMPENSATION ACCELEROMETER Russian patent published in 2012 - IPC G01P15/13 

FIELD: physics.

SUBSTANCE: accelerometer has a sensitive element, an angle sensor, a torque sensor, a positive and a negative feedback, phase detectors for the positive and negative feedback. A controlled relay element and a level converter are connected in series on data inputs in the negative feedback from the output of an integrating amplifier, the input of which is connected to the output of the phase detector of the negative feedback, to additional inputs of standby synchronous generators. A ripple filter, a dynamic error control unit and a voltage-to-current converter are also connected in series in the positive feedback from the output of the phase detector of the positive feedback to the additional input of the adder, and the output of the adder is connected the input of the torque sensor.

EFFECT: introduction of a dynamic error control unit, a controlled relay element and a high-speed digital filter in the compensation accelerometer enables to design a device with a digital output, high accuracy and wide bandwidth.
