COMPENSATION ACCELEROMETER Russian patent published in 2014 - IPC G01P15/13 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement equipment and is designed for use in devices of compensation type with a digital outlet in systems of stabilisation, navigation and homing. The compensation accelerometer comprises a sensitive element, an angle sensor, an amplifier, a phase detector of negative feedback, an integrating negative feedback from the outlet of the comparator to the inlet of the torque sensor via serially connected comparator, level converter, a pair of waiting synchronous generators, reversible binary counter, comparison circuit, trigger, electronic key, connected by information inlets. Besides, the local negative feedback is introduced from the amplifier outlet to the inlet of the phase detector of negative feedback via serially connected summator, threshold element, integrating and differentiating link and delay link connected by information inlet. The outlet of the phase detector of the negative feedback is connected to the inlet of the comparator via a differentiating link. The outlet of the reversible binary counter is a digital outlet of the compensation accelerometer.

EFFECT: introduction of a local negative feedback into a compensation accelerometer makes it possible to stabilise parameters of a compensation accelerometer, and implementation of an integrating-differentiating and differentiating link in the integrating negative feedback makes it possible to increase accuracy of measurement and to expand pass bad due to implementation of the astable mode.
