Abstract:
1. An arrangement for measuring a rate of rotation comprising a vibration sensor, the vibration sensor comprising: a plurality of capacitive drive elements configured to rotationally vibrate the ring and measure the vibration of the ring perpendicular to the first axis; a plurality of capacitive measuring elements configured to measure a rotation of the disk in a second axis, which is excited by rotation in a third axis under the action of a Coriolis force, the capacitive drive elements and the capacitive measuring elements each respectively comprising: a plurality of capacitive vibration measuring elements configured to measure the excited vibration of the disk, the plural capacitive vibration measuring elements supplied with an AC voltage at a first measuring frequency which is higher than the frequency of the excitation voltages, wherein the fixed electrodes of the capacitive measuring elements are supplied with AC voltages at a second measuring frequency which differs from the first measuring frequency and is higher than the frequency of the excitation voltages.
