COMPENSATION ACCELEROMETRE Russian patent published in 2011 - IPC G01P15/13 

FIELD: instrument making.

SUBSTANCE: accelerometre includes two local feedbacks of opposite signs. Positive feedback is formed from the amplifier output to voltage-current converter input through phase detector of positive feedback and filter of upper frequencies. Integrating negative feedback is formed on the amplifier output to input of adder subsequently via information inputs through phase detector of negative feedback, integrating amplifier, signal varying speed limit device, comparator unit, level converter, pair of triggered synchronous generators, reversible binary counter, comparison diagram, trigger, electronic switch the input of which is connected to the current generator output. Output of reversible binary counter is digital output of compensation accelerometre.

EFFECT: invention allows enlarging the pass band and improving accuracy.
