| 摘要 |
The gyrometer, which can be produced at low cost, has a detector member (10) consisting of a substantially flat plate (12) constituting at least 8-fold symmetry consisting at least mostly of piezoelectric material and whose two large faces carry both electrodes (EM) for exciting the plate in resonance, distributed uniformly about the axis of the plate, and electrodes (DC) for detecting the vibrations in the plate, located in the same plane as the excitation electrodes and placed so as to detect the stresses caused by the driving field due to the excitation electrodes (EM) and by the Coriolis field when the plate turns about the sensitive axis, constituted by its axle. The gyrometer has a circuit for supplying the electrodes (EM) for exciting the plate in resonance which is intended to give the plate (12) resonance in tangential lobes. <IMAGE>
