Sensor device. |
摘要 |
<p>A pressure sensor includes a resonator element (14) mounted on an optical fibre ferrule (11) whereby light signals for maintaining the resonator in a state of oscillation and for returning a modulated signal to a remite station are coupled to the resonator. The resonator is located in an evacuated cavity (16) and is mounted on a flexible diaphragm (13) whereby pressure changes may be detected as changes in the resonant frequency.</p> |
