24VDC Magnetostrictive Liquid Level Meter With LCD Display
Working Principle of 24VDC Magnetostrictive Liquid Level Meter With LCD Display
The magnetostrictive liquid level gauge is mainly composed of three parts: electronic transmitter, floating ball, and detection rod. When working, the floating ball rises or falls with the liquid level along the conduit. The floating ball is equipped with a permanent magnet and forms a magnetic field around it; the electronic transmitter periodically sends out a current pulse, called the initial pulse, which propagates down the magnetostrictive line. , a magnetic field is also generated around it during the downward movement; the moment the two magnetic fields meet, a torsion force is generated, which acts on the magnetostrictive line to form a return pulse. The pulse travels upward at a fixed speed and is received by the electronic transmitter. Using the principle of Weidmann effect (the working principle of magnetostriction), and by means of modern advanced electronic technology, the liquid level height can be accurately measured by measuring the time interval between the initial pulse and the return pulse. The liquid level gauge produced by this method is the most accurate, simple, stable, reliable and mature product in the field of liquid level measurement. Especially in the common environment such as small range, normal temperature and normal pressure, it has unique advantages and is incomparable with other measurement methods.
Design feature of 24VDC Magnetostrictive Liquid Level Meter With LCD Display
◎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
