Description

Technical Field

[0001] The invention belongs to the technical field of liquid level sensors, and in particular relates to a magnetostrictive liquid level interface sensor. Background Art

[0002] The magnetostrictive liquid level sensor is a high-precision, ultra-long-stroke absolute position measurement sensor manufactured using the magnetostrictive principle. It can not only measure the linear displacement of a moving object, but also provide analog signals of the displacement and speed of the moving object. The working principle is that when measuring, the pulse generator generates a waveguide pulse, which is converted into a current pulse propagating along the waveguide line after being processed by the electronic part, namely the start pulse. The magnetic field generated by it is superimposed on the magnetic field formed by the magnetic ring to generate instantaneous torque, causing the waveguide line to twist and generate a tension pulse. This pulse is transmitted back along the waveguide line at a fixed speed, generating an induced current pulse, namely the end pulse, at both ends of the coil. By measuring the time difference between the start pulse and the end pulse, the liquid level or displacement can be accurately measured.

[0003] In actual use, some existing magnetostrictive liquid level interface sensors need to install flanges of different specifications on the detection rod according to actual conditions, and then connect them together through the flanges and bolts. Since there are many bolts installed, the screw hole positions are easily offset during installation, resulting in inconvenience in installation. In addition, some existing magnetostrictive liquid level interface sensors need to be repaired. During long-term use, liquid is easily adhered to the surface of the detection rod, which is inconvenient to clean and leads to inaccurate detection. Summary of the Invention
