COMPENSATING ACCELEROMETER Russian patent published in 2017 - IPC G01P15/13 

FIELD: measurement equipment.

SUBSTANCE: pending compensating accelerometer comprising sensor, angle sensor, whose output is connected to the amplifier input, torque sensor, the negative feedback, the phase detector of negative feedback integrator, whose input is connected to the output of the amplifier. Additional sensor inputs and the phase angle detector negative feedback integrator connected to the output of the reference voltage generator. The output of phase detector negative feedback integrator connected to the input of the integrating amplifier, the outputs of which are connected to inputs of synchronous generators of the waiting pair via a controllable relay element and a level converter. Outputs of the waiting pair synchronous generator connected to the input of the binary multiplier via series connected Information inputs reversible binary counter transducer additional code in direct scheme and collection, and the output of the binary multiplier is connected via a digital filter having one of the inputs of the sign switch, the other input of which is connected to the output reversible binary counter. The output of the iconic selector is connected to an input torque sensor through the adder. The output of the binary multiplier is a digital output. Additional inputs couples waiting for synchronous generators controlled relay element connected to the output of the clock circuit. The negative feedback error introduced by the dynamic control unit having an input connected to the output of the phase detector through a negative feedback smoothing filter, and an error output dynamic control unit is connected to one input of the adder through a voltage-current converter. In addition, the output relay managed element is connected to the analog input of the filter with the transfer function (where T - time constant, s - Laplace transform operator) and the analog output of the filter is an analog output device.

EFFECT: improved accuracy and bandwidth extension.
