Technical Field
The utility model relates to the technical field of material level detection, in particular to a device for preventing a floating ball from being blocked by a magnetostrictive liquid level meter.
Background
When the sensor of the magnetostrictive liquid level meter works, a circuit part of the sensor excites pulse current on the waveguide wire, and the pulse current magnetic field is generated around the waveguide wire when the current propagates along the waveguide wire. A float is arranged outside a measuring rod of a sensor of the magnetostrictive liquid level meter, and the float can move up and down along the measuring rod along with the change of the liquid level. A group of permanent magnetic rings is arranged in the floater. When the pulse current magnetic field meets the magnetic ring magnetic field generated by the floater, the magnetic field around the floater changes, so that the waveguide wire made of magnetostrictive material generates a torsional wave pulse at the position of the floater, and the pulse is transmitted back along the waveguide wire at a fixed speed and is detected by the detection mechanism. The position where the float is located, i.e. the position of the liquid level, can be accurately determined by measuring the time difference between the pulse current and the torsional wave. Because the measuring rod is in the liquid containing impurities for a long time, after the measuring rod leaks out of the liquid level, the measuring rod is influenced by temperature and time, so that a large amount of impurities are attached to the measuring rod, the floating ball moves up and down, the liquid level height cannot be measured in real time, and potential safety hazards are brought to detection.
In order to overcome the above-mentioned disadvantages, the conventional solution is to periodically remove the level gauge and wash the measuring rod with wash oil so that the surface of the measuring rod remains smooth. However, in the process of producing production, the removal of the liquid level meter can affect the production monitoring and waste manpower and material resources.
