Working Principle
Magnetostrictive Level Transmitter consists of three parts: the detection rod, the circuit unit and the float.
During the measurement, the circuit unit generates a current pulse that travels down the magnetostrictive line and creates a circular magnetic field. A float is attached to the outside of the probe rod and moves up and down along the rod in response to changes in liquid level.
Since the float is equipped with a set of permanent magnets, the float simultaneously generates a magnetic field. When the current magnetic field meets the float magnetic field, a "distortion" pulse, or "return" pulse, is generated. The time difference between the "return" pulse and the current pulse is converted into a pulse signal, which calculates the actual position of the float and measures the liquid level. At the same time, the transmission module of Magnetostrictive Level Transmitter adopts standard output signals, which is convenient for the computer to process the signals, and it is easy to realize network work and improve the automation of the entire measurement system.
Product Advantages
High reliability
Magnetostrictive Level Transmitter adopts the waveguide principle and has no mechanical movable parts, so there is no wear and tear. The whole transducer is enclosed in a stainless steel tube, and the measuring medium is not in contact. The sensor works reliably and has a long life.
High precision
Magnetostrictive Level Transmitter works by measuring the time of the starting pulse and the ending pulse to determine the measured displacement. Therefore, the measurement accuracy is high and the resolution is better than 0.01% F.S. 3.
High safety
Magnetostrictive Level Transmitter has high explosion-proof performance, intrinsically safe and explosion-proof, safe to use. It is especially suitable for the measurement of chemical materials and flammable liquids. No need to open the tank lid when measuring, avoiding the unsafe manual measurement.
Easy to install
Magnetostrictive Level Transmitter is generally installed through the existing pipe opening at the top of the tank, especially suitable for the installation of underground storage tanks and tanks already in operation, and can not affect normal production during the installation process.
