24VDC Two Wire Magnetostrictive Level Gauge For Liquid Measure

Working Principle of 24VDC Two Wire Magnetostrictive Level Gauge For Liquid Measure

The magnetostrictive level gauge consists of three parts: the detection rod, the circuit unit and the float. During measurement, the circuit unit generates a current pulse that travels down the magnetostrictive wire and generates a ring-shaped magnetic field. There is a float outside the detection rod, and the float moves up and down along the detection rod with the change of the liquid level. Since a set of permanent magnets are installed in the float, the float generates a magnetic field at the same time. When the current magnetic field meets the float magnetic field, a "twist" pulse, or "return" pulse, is generated. Convert the time difference between the "return" pulse and the current pulse into a pulse signal, so as to calculate the actual position of the float and measure the liquid level.

Design feature of 24VDC Two Wire Magnetostrictive Level Gauge For Liquid Measure

◎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
