FIELD: instrument engineering.
SUBSTANCE: invention is designed for being used as sensing element of stabilisation and navigation systems and can be used in measuring devices of mechanical quantities of compensation type. Compensation accelerometre consists of in-series connected, at data inputs, sensing element, angle sensor, and preliminary and selective amplifiers engaged with one of negative feedbacks. Introduction of two negative feedbacks (analogue and digital) into compensation accelerometre, which include amplifiers, high pass filter, comparing unit, signal level converters, logic OR diagrams, phase shifter, logic blocks, reversible binary counters, summing units, binary multiplier, current generator, and electronic switch allowed to design the device for measuring accelerations with extended band pass and with astatism as to deviation owing to introduction of binary multiplier into digital negative feedback.
EFFECT: improving accelerometre operation characteristics.
