4-20mA Magnetostrictive Liquid Level Meter With 0.5mm High Accuracy
Working Principle of 4-20mA Magnetostrictive Liquid Level Meter With 0.5mm High Accuracy
There is a float outside the sensor measuring rod of the magnetostrictive liquid level gauge, which can move up and down along the measuring rod with the change of the liquid level. Inside the float there is a set of permanent magnetic rings. When the magnetic field of the pulse current meets the magnetic field of the magnetic ring generated by the float, the magnetic field around the float changes so that the waveguide wire made of magnetostrictive material generates a torsional wave pulse at the position of the float. The waveguide wire is returned and detected by the detection mechanism. By measuring the time difference between the pulse current and the torsional wave, the position of the float, that is, the position of the liquid surface, can be accurately determined. The technical advantages of the magnetostrictive liquid level gauge: the magnetostrictive liquid level gauge is suitable for the liquid level measurement of the clean liquid level with high precision requirements, and the accuracy can reach 1mm, and the accuracy of the latest product can reach 0.1mm. Magnetostrictive level gauges can also be used to measure the interface between two different liquids. The explosion-proof design is suitable for hazardous occasions. The intelligent electronic circuit design can calculate the volume; the only movable part is the float, and the maintenance is extremely low.
Design feature of 4-20mA Magnetostrictive Liquid Level Meter With 0.5mm High Accuracy
◎Wider applicability, with multiple probe forms, multiple process connection forms, multiple manufacturing materials, and customizable design
◎ strong reliability: since the magnetostrictive liquid level gauge adopts the waveguide principle, there is no mechanical movable part, so there is no friction and wear. The whole converter is enclosed in a stainless steel tube, which is non-contact with the measuring medium. The sensor works reliably and has a long service life
◎ high accuracy: since the magnetostrictive liquid level meter works with waveguide pulse, the measured displacement is determined by measuring the time of the start pulse and the end pulse, so the measurement accuracy is high and the resolution is better than 0.01% FS, which is difficult to achieve with other sensors
◎ high safety: the magnetostrictive liquid level meter has high explosion-proof performance, intrinsic safety and 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 cover during the measurement to avoid the insecurity of manual measurement.
◎ magnetostrictive liquid level meter is easy to install and easy to maintain: the magnetostrictive liquid level meter is generally installed through the existing pipe orifice on the tank top, especially suitable for the installation of underground storage tanks and storage tanks that have been put into operation, and normal operation can not be affected during the installation process
