COMPENSATION ACCELEROMETER Russian patent published in 2013 - IPC G01P15/13 

FIELD: measurement equipment.

SUBSTANCE: compensation accelerometer includes a sensitive element, an angle sensor, an integrating feedback amplifier, a moment sensor, and electronic switch, a threshold element, and additional integrating amplifier, negative feedbacks, an integrating amplifier, a phase negative feedback detector, a voltage-current converter; two adders, broad-band and smoothing filters, and local negative feedback; at that, input of broad-band filter is connected to output of phase detector of negative feedback, and output is connected to input of comparator through the second adder and additional integrating amplifier, which are in series connected as to information inputs. Local negative feedback is implemented from the comparator output to one of the inputs of the second adder through smoothing filter.

EFFECT: introduction to accelerometer of negative feedbacks with broad-band and smoothing filters allows creating the device operating in self-oscillation mode, with astatism as to deviation, with enlarged broad band and improved accuracy.
