PIEZOELECTRIC VIBRATION GYROSCOPE (VERSIONS) Russian patent published in 2011 - IPC G01C19/56 G01P9/04 

FIELD: instrument making.

SUBSTANCE: as per the first and the second versions, gyroscope includes cylindrical thin-wall resonator from piezoelectric material, on inner surface of which solid electrode is formed, and two pairs of diametrically located opposite segmental electrodes are formed on outer surface. As per the first version, gyroscope also includes two potentiometers, self-sustained oscillator and in-series connected differential amplifier, synchronous detector, smoothing filter and voltage amplifier. As per the second version, gyroscope includes potentiometer, self-sustained oscillator and in-series connected differential amplifier, synchronous detector, smoothing filter and voltage amplifier.

EFFECT: invention allows improving measurement accuracy of angular velocity and sensitivity of piezoelectric vibration gyroscope.
