When the sensor of the magnetostrictive liquid level gauge is working, the circuit part of the sensor will excite a pulse current on the waveguide wire, and the current will generate pulses around the waveguide wire when it propagates along the wave WXH-2Q01 magnetostrictive liquid level gauge guide wire Electric current magnetic field. The sensor rod of the magnetostrictive liquid level gauge is equipped with a float, which can move up and down along the rod with the change of liquid level. There is a set of permanent magnetic rings inside the float. When the pulse current magnetic field meets the magnetic ring magnetic field generated by the float, the magnetic field around the float changes so that the waveguide wire made of magnetostrictive material generates a torsional wave at the position of the float. Pulse, this pulse travels back along the waveguide filament at a fixed speed and is detected by the detection mechanism. By measuring the time difference between the pulse current and the torsion wave, the position of the float, that is, the position of the liquid surface, can be determined with high accuracy. The technical advantages of magnetostrictive level gauges: Magnetostrictive level gauges are suitable for high-precision clean liquid level measurement, with an accuracy of 1mm, and the accuracy of the new product can reach 0.1mm. Magnetostrictive liquid level gauges can also be used to measure the interface between two different liquids. The explosion-proof design is suitable for dangerous occasions. The intelligent electronic circuit design can calculate the volume; the whole is a movable part as a float, so the maintenance is extremely low.

    1. Strong reliability: Since the magnetostrictive level gauge adopts the waveguide principle, there is no mechanical movable part, so there is no friction and no wear. The whole transducer is enclosed in a stainless steel tube and has no contact with the measuring medium. The sensor works reliably and has a long life.

    2. High accuracy: Since the magnetostrictive level gauge works with waveguide pulses, the measured displacement is determined by measuring the time of the initial pulse and the end of the pulse during work, so the measurement accuracy is high, and the resolution is better than 0.01% FS. It is an accuracy that is difficult to achieve with other sensors.

    3. Good safety: The magnetostrictive level gauge has high explosion-proof performance, intrinsically safe explosion-proof, safe use, and is especially suitable for the measurement of chemical raw materials and flammable liquids. There is no need to open the tank lid during measurement, to avoid the insecurity of manual measurement.

    4. Magnetostrictive level gauge is easy to install and simple to maintain: Magnetostrictive level gauges are generally installed through the existing nozzles on the top of the tank, and are especially suitable for the installation of underground storage tanks and tanks that have already been put into operation. The process does not affect normal production.

    5. Facilitate system automation: the secondary instrument of the magnetostrictive level gauge adopts standard output signals, which is convenient for the microcomputer to process the signals, and it is easy to realize networking work and improve the automation degree of the entire measurement system.
