ARRANGEMENT FOR MEASURING A RATE OF ROTATION USING A VIBRATION SENSOR

摘要

The arrangement has a vibration sensor (2) i.e. vibration gyroscope, whose vibration is initiated perpendicular to an axle using capacitive drive units (11-14). Capacitive units are formed by fixed electrodes (18, 18`) and by electrodes (17) that are connected with fixed connection and are movable with the vibration sensor. Exciting voltages are supplied to the fixed electrodes of the capacitive units, whose frequency corresponds to the resonant frequency or sub harmonic of the resonance frequency of the capacitive drive units.
