DEVICE FOR MEASUREMENT OF ACCELERATIONS Russian patent published in 2008 - IPC G01P15/13 

FIELD: mechanics.

SUBSTANCE: invention proposes a sensitive element in systems of stabilisation, navigation and guidance to be used in compensation-type devices of measurement of mechanical magnitudes. The device contains a sensitive element, a pickup of angle, a pickup of moments looped with a feedback path, and an analog and digital channels. The analog channel enters, from the angle pickup output via a differential amplifier, 2^nd-order filter, PI-element, voltage-to-current converter connected in series, to the input of pickup of moments. The digital channel is arranged between the output of the 2^nd-order filter and the input of the final register and incorporates an adder, the first comparator, a pair of triggered synchronous generators, an asynchronous RS-trigger, the first and second AND circuits, the first reversible binary counter. The differential amplifier, PI-element, comparators, the trigger, AND circuits, reversible binary counters and the final register allow increasing the mode gain in open circuit, the accuracy of analog and digital readout in the steady-state conditions and to expand the bandwidth. Besides, the current information on acceleration in the digital channel is displayed not in discrete time intervals but continuously to add to measurement accuracy.

EFFECT: higher accuracy of analog and digital readout in steady-state conditions and expanded bandwidth.
