COMPENSATION ACCELEROMETRE Russian patent published in 2010 - IPC G01P15/13 

FIELD: physics.

SUBSTANCE: invention is designed for use as a detecting element in stabilisation and navigation systems and can be used in devices for measuring compensation type mechanical quantities. The accelerometre has a detecting element, an angle sensor, a feedback integrating amplifier, a torque sensor, an electronic switch, a threshold element, an extra integrating amplifier and two negative feedback circuits, one from the output of the angle sensor to the input of the adder through the following components which are connected in series on data inputs: integrating amplifier, negative feedback phase detector, voltage-to-current converter, and the other from the output of the negative feedback phase detector to the input of the adder through the following components which are connected in series on data inputs: ripple filter, extra integrating amplifier, comparator, level transducer, pair of standby synchronous generators, bidirectional binary counter, comparator circuit, threshold element, electronic switch whose input is connected to the output of the current generator.

EFFECT: use of two negative feedback circuits enables design of a device which operates in astable mode with absence of offset and wider transmission band.
