[0002] The magnetostrictive liquid level sensor is a high-precision, super-long stroke absolute position measurement sensor manufactured by using the magnetostrictive principle, which can not only measure the linear displacement of a moving object, but also provide displacement and speed analog signals of the moving object. When measuring, the pulse generator generates a waveguide pulse, which is converted into an electric current pulse propagating along the waveguide line after being processed by the electronic part, i.e., the start pulse. The magnetic field generated by the start pulse and the magnetic field formed by the magnetic ring are superimposed, generating a transient torsion force that causes the waveguide line to twist and generate a tension pulse. This pulse propagates along the waveguide line at a fixed speed, generating an induced current pulse at both ends of the coil, i.e., the end pulse. By measuring the time difference between the start pulse and the end pulse, the liquid level or displacement can be accurately measured.
