摘要
FIELD: instrumentation engineering. SUBSTANCE: in presence of acceleration on measurement axis of device its pendulum sensitive element 1 deviates to certain angle under action of moment of inertia. Displacement of sensitive element 1 is measured and converted into electric signal by displacement sensor 2. After amplification and conversion in amplifier 3 current creating compensation moment is fed into compensation coil of inverse converter 4. After feeding of frequency alternating current into compensation coil of inverse converter 4 one seeks after equality of currents of inverse converter under changes of static acceleration and with feeding of alternating current as well as after equal displacements of sensitive element 1. EFFECT: increased precision of determination of nonlinearity of characteristic of accelerometer. 7 dwg
