NYCZ500 Magnetostrictive Level Gauge for Liquid-liquid Interface Measurement with High Reliability
NYCZ500 Magnetostrictive Level Gauge Working Principle
The product mainly consists of a measuring rod, an electronic chamber and a non-contact floating ball sleeved on the measuring rod. Magnetostrictive wire (waveguide wire) is installed in the measuring rod. The measuring rod is made of non-magnetic stainless steel tube, which protects the waveguide wire very well.
When the magnetostrictive liquid level meter is working, the pulse generator in the electronic chamber sends out a starting pulse. When this starting pulse is transmitted in the waveguide wire, it generates a rotating magnetic field moving in the direction of the waveguide wire. When this magnetic field meets the permanent magnetic field in the float ball, it generates a magnetostrictive stretching effect, causing the waveguide wire to twist and generate a constant speed mechanical wave. This mechanical wave propagates in two directions. The mechanical wave reaching the end of the measuring rod is absorbed by the damper. The mechanical wave transmitted back to the electronic chamber is sensed by the energy pickup mechanism installed in the electronic chamber and converted into the corresponding current pulse. The energy pickup mechanism calculates the time difference between the two pulses to accurately measure the height of the measured liquid level.
NYCZ500 Magnetostrictive Level Gauge Design Features
1. Wide applicability: a variety of probe forms, a variety of process connection forms, a variety of production materials, can be customized design;
2. Reliability: As the magnetostrictive level meter adopts the waveguide principle, there is no mechanical moving part, so there is no friction, no wear. The entire converter is enclosed in a stainless steel tube, and the measurement medium non-contact, reliable sensor work, long life.
3. High accuracy: Since the magnetostrictive level meter works with waveguide pulse, the measured displacement is determined by measuring the time of the starting pulse and the ending pulse, so the measurement accuracy is high and the resolution is better than 0.01%FS, which is difficult to achieve the accuracy with other sensors.
