METHOD OF DETERMINING ZERO SHIFT OF PENDULUM COMPENSATION ACCELEROMETER

摘要

FIELD: measuring engineering. ^ SUBSTANCE: method comprises setting the pendulum and axis of the accelerometer in the horizontal plane, measuring feedback signals for two opposite positions of the axis of sensitivity, rotating the housing of the accelerometer with disconnected feedback around the axis of the pendulum to obtain zero signal from the angle pickup, and rotating the housing of the accelerometer by 90° around the axis of the pendulum to return it to the initial position. Before measuring the signal of feedback, the signal from the angle pickup is set to zero by means of the amplifier unbalance. ^ EFFECT: enhanced precision. ^ 1 dwg
