METHOD OF MEASURING ERROR OF PROPORTIONALITY OF PENDULUM DIGITAL ACCELEROMETER Russian patent published in 2006 - IPC G01P15/08

Abstract SU 1839865 A1

FIELD: measuring engineering.

SUBSTANCE: method comprises comparing the integral value of the output information from the accelerometer with its reference value. The integral values of the output information to be compared are obtained in two cycles of measurements of same duration. In one of the cycles the negative feedback of the accelerometer is disconnected for a short-term period. The duration of the disconnection pause is chosen to prevent the pendulum of the sensor to be in a contact with stops.

EFFECT: enhanced precision and improved resolution.
