METHOD TO DETERMINE POLARITY OF SENSITIVE ELEMENT OF PENDULUM-TYPE COMPENSATING ACCELEROMETER

摘要

FIELD: instrument making.;SUBSTANCE: sensitive element polarity is checked up by measuring the angle pickup output signal on feeding the current to the feedback circuit. Here, the angle pickup output voltage polarity is measured at a position when the accelerometer sensitivity axis positive direction gets aligned with that of acceleration of gravity before and after feeding direct current to actuator winding creating the moment exceeding that created by acceleration of gravity. The angle pickup output voltage allows estimating the correctness of the sensitive element circuit connection.;EFFECT: higher manufacturability.
