METHOD FOR DETERMINING PARAMETERS OF PRECISION QUARTZ PENDULUM ACCELEROMETER Russian patent published in 2014 - IPC G01P21/00 

FIELD: measurement equipment.

SUBSTANCE: according to the method, an accelerometer is located in the first position on a movable base, at which a sensitivity axis of an accelerometer plate lies in the plane of horizon perpendicular to the horizontal rotation axis of the base; electrical signals U_offset calibrated as to level and sign are supplied to the first input of a feedback device; output signal U_output and offset signal $$U_{offset}^{\ast }$$ are measured at the second input of the feedback device and dependence of U_output on $$U_{offset}^{\ast }$$ is determined ("output signal" - "offset signal" static characteristic of the accelerometer) for each signal U_offset; the base is turned through a small angle and the above actions are repeated; then, parameters of the accelerometer are calculated.

EFFECT: possible forecasting of stability of position of the sensitivity axis at offset of centre of mass of the sensitive element due to zero drift from the side of the input of the feedback device, as well as the level of the output signal of the accelerometer at no acceleration of gravity force.
