Pressure transducer |
| 摘要 |
The invention provides a pressure transducer comprising: a closed container (5) having a pair of opposed interior walls (6 and 7) between which is disposed a magnetostrictive element (1); means (9 and 10) to create a magnetic field within the element so as to energise it; and means (11) to detect the resonant frequency of the element, thereby to produce an output indicative of the pressure exerted on the transducer.
