COMPENSATION ACCELEROMETER Russian patent published in 2022 - IPC G01P15/13 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology. From the output of the angle sensor to one of the inputs of the comparator, a phase detector, a threshold element with an ambiguity zone, a nonlinear element with a dead zone, an adder are introduced into the compensation accelerometer from the output of the angle sensor to one of the inputs of the comparator, and one of the inputs of the threshold element with an ambiguity zone is connected to one of the outputs of the phase detector. detector, and the output of the threshold element with an ambiguity zone is connected to one of the inputs of the adder, in addition, one of the outputs of the reference voltage generator is connected to one of the inputs of the phase detector and one of the inputs of the adder is connected to the output of the phase detector through a nonlinear element with a dead zone, except In addition, one of the inputs of the threshold element with an ambiguity zone is connected to the output of the auxiliary frequency generator, in addition, a high-pass filter is introduced, the input of which is connected to the output of the comparison circuit, and the output is connected to the input of the trigger and the output of the reversible binary counter is digital compensation accelerometer output.

EFFECT: bandwidth expansion, measurement accuracy improvement.
