摘要： A magnetostrictive position transducer and a magnetostrictive sensing element thereof are characterized that a magnetostrictive sensing element is mounted inside an outer tube, the magnetostrictive sensing element has two end mounts respectively mounted on two ends of an insulating and hollow tube and a magnetostrictive wire mounted through the tube, the magnetostrictive wire has two wire adapters respectively mounted on two ends of the magnetostrictive wire and respectively mounted in the end mounts so that the magnetostrictive wire is contactlessly mounted through the tube, a sensing module is mounted in one of wire adapter to sense signal variation on the magnetostrictive wire. With the foregoing structure, the magnetostrictive sensing element does not require devices for applying pre-stress and damping, thereby simplifying structure and ensuring high stability in measurement of the magnetostrictive position transducer.
