| 摘要 |
The invention relates to a sensor device (1) for MDL, MI or REF operating modes, comprising an elongated magnetostrictive sensor element (2), which is provided at one end with an excitation coil (5) and at the other end with a measuring coil (6), which is held by fixing elements (3, 4) at both ends and which can be or is subjected to a mechanical pre-stress with the aid of said fixing elements (3, 4). According to the invention, the magnetostrictive sensor element (2) is pre-magnetised and the fixing elements (3, 4) provide an electrical connection for the magnetostrictive sensor element (2). |
