.
The magnetostrictive liquid level sensor is designed based on the magnetostrictive principle. It consists of the sensing element waveguide wire (tube), a movable magnet, and electronic components that emit electrical pulse signals and receive and return models. When the electric pulse generated by the pulse generator in the electronic probe is transmitted along the waveguide wire in the steel pipe, the electric pulse is accompanied by a circular magnetic field perpendicular to the waveguide wire and transmitted along the waveguide wire at the speed of light. When the pulsed toroidal magnetic field meets the intrinsic magnetic field of the float, the magnetic field vectors of the two are superimposed to form a helical magnetic field, which generates an instantaneous torque and forms a mechanical torsional wave on the waveguide wire, which is transmitted back to the electronic probe at the speed of sound to cause an induced pulse at both ends of the coil. By measuring the time difference between the power generation pulse and the induction pulse generated by the torsion wave return, the measured liquid level can be accurately calculated. At the same time, the temperature sensor can be continuously measured in the measuring rod.
