UHF Magnetostrictive Level Gauge Working Principle
The UHF-C magnetostrictive level gauge is developed according to the principle of magnetostriction, and it is a new generation of high-precision measurement level gauge.
When the magnetostrictive level gauge is working, the transmitter circuit outputs an excitation pulse current, and the pulse current propagates along the magnetostrictive line and generates a pulse current magnetic field.
The sensor rod of the magnetostrictive liquid level gauge is equipped with a magnetic float, and the float moves along the rod with the change of the liquid level.
A permanent magnetic ring is installed inside the float. When the pulse current magnetic field meets the magnetic ring magnetic field of the float, the magnetic field around the float changes so that the magnetostrictive wire generates a torsional wave pulse at the position where the float stays. This pulse is at a fixed speed. It is transmitted back to the transmitter along the magnetostrictive line and detected by the detection circuit.
The central processor calculates the time difference between the pulse current and the torsion wave pulse to accurately determine the position of the float, that is, the position of the liquid surface.
Transmitter analog-to-electric conversion circuit outputs 4-20mA signal or RS485 MODBUS signal, so as to realize the purpose of remote transmission of liquid level signal.
