The magnetostrictive displacement sensor utilizes the magnetostrictive principle to accurately measure the position by generating a strain pulse signal through the intersection of two different magnetic fields. The measuring element is a waveguide tube, and the sensitive element in the waveguide tube is made of special magnetostrictive material. The measuring process is that a current pulse is generated in the electronic chamber of the sensor, and the current pulse is transmitted in the waveguide tube, so that a circumferential magnetic field is generated outside the waveguide tube, and when the magnetic field intersects with the magnetic field generated by the movable magnetic ring 15 which is sleeved on the waveguide tube and used as a position change, a strain mechanical wave pulse signal is generated in the waveguide tube under the action of magnetostriction, and the strain mechanical wave pulse signal is transmitted at a fixed sound speed and is quickly detected by the electronic chamber.
