Method of and apparatus for compensating for material instabilities in piezoelectric materials. |
| 摘要 |
<p>The vibrating rate sensor (10) for detecting rotational movement about an axis (X) is provided with means for measuring the resonant frequency of the cylinder (12) and the operating temperature and means for compensating for temperature and ageing instabilities within the piezoelectric materials incorporated in the cylinder (12). <IMAGE></p> |
