Magnetostrictive liquid level gauge can be used to measure the boundary between two different liquids. Explosion-proof design, suitable for dangerous situations, intelligent electronic circuit design can calculate the volumetric capacity; the only movable part is the floater, and the maintenance amount is extremely low.
The core of the magnetostrictive level gauge sensor consists of a ferromagnetic material measuring sensing element, commonly referred to as a "waveguide", a permanent magnet that can be moved, and a longitudinal magnetic field generated by the magnet and the waveguide. When a current pulse (ie, an "interrogation signal") is sent from the sensor head and passes through the waveguide, the second magnetic field is created by the radial aspect of the waveguide. When the two magnetic fields intersect at the waveguide, the waveguide produces a “magnetostrictive†appearance, and a strain pulse is generated instantaneously. This pulse, called the return signal, is generated from the point at which the ultrasonic signal is generated (ie, the position measurement point). The sensor head is returned to the sensor and detected by the detector.
Magnetostrictive liquid level meter advantages and disadvantages:
advantage:
1. The magnetostrictive liquid level gauge is suitable for liquid level measurement of high-precision required cleaning level, with an accuracy of 1mm, and the latest product accuracy can reach 0.1mm. 2.
2. Can be applied to the boundary measurement between two different liquids.
3. The greatest advantage of magnetostrictive is its extremely high resolution, which can be achieved in micron scale. A typical application is to measure the position of the load cylinder of the mill. However, the design here is not the same as the level measurement. The position measurement of the hydraulic cylinder is not the hydraulic oil driving the magnetic ring (ie, the float), but the movable part of the cylinder moves the magnetic ring through the mechanical structure, so the position is very clear. In general, the precision required for the plate thickness of the rolling mill is usually several to several tens of micrometers. Therefore, the resolution of the magnetostrictive sensor must reach the micron level.
4. Explosion-proof intelligent electronic circuit design can calculate the volumetric capacity
5. The only movable part of the magnetostrictive level gauge is the float, and the maintenance amount is extremely low. The liquid level measurement environment applied to various types of tanks is highly adaptable and easy to install.
Compared with radar and other liquid level gauges in short-range measurement, its cost-effectiveness is very high, and its function is also many. The display has current, temperature, and interface display. This is exactly what magnetostrictive level gauges have become one of the most commonly used products in metering tanks such as gas stations today.
Disadvantages:
1, slightly less anti-interference ability (usually not recommended for use in power plants and other places with strong electromagnetic radiation).
2, must be contact measurement, but the real measurement unit is not in contact with the liquid, contact with the liquid is his protective tube.
3, direct contact with the media, floating ball sealing requirements must be strict, can not measure viscous media.
4, limited installation. Higher installation and maintenance requirements have led to less widespread market adoption.
