Remote transfer of magnetic flip plate level gauge
Far transfer is the combination of the two parts of the basic type and the remote transmitter, which can realize the signal transmission, the level alarm and the control function. UHZ type magnetic level gauge turning intuitive, smart and high cost performance, heat resistance, compression, the characteristics of anti-corrosion, explosion-proof, make it widely used in electric power, petroleum, chemical industry, metallurgy, environmental protection and other industries the liquid level measurement and automatic control in the process of production.
The principle of the liquid level of the magnetic flip board
The liquid level of the magnetic flip plate is developed by the principle of buoyancy and magnetic coupling. When the measured liquid level fluctuation of the container, the float liquid level gauge led tube with lifting, float in the permanent magnets by magnetic coupling is passed to the indicator, drive the red, white double column turn 180 degrees, when the liquid level rises, double column from white to red, when the liquid level drops, double column from red to white, indicator of red, white for the containers within the medium level the actual height of the world level, so as to realize liquid level instructions.
The electrical signal of the magnetoboard liquid level is carried out by the combination of the basic and the liquid. Liquid level far eastone device by UR resistance sensor and UB R/I conversion module, the transmitter's sensor is fixed in the form of binding on the outside of UHZ type magnetic level gauge turning led tube, make its level gauge the same magnetic coupling system. When magnetic float move up and down with the liquid level, the corresponding level position of dry reed pipe suction, the effect of the magnetic field inside the float chain value changes, through the resistance of the signal conversion module will change into two wire 4 ~ 20 madc standard output signal, the signal can be easily and electric type III instruments and display systems, can also with light indicator, digital display adjusting alarming device, so as to achieve remote magnetic flap liquid level gauge for the purpose of display, control, regulation and alarm.
Magnetic level gauge control and alarm is turning through the dry reed pipe or mercury contact switch, according to the given value movement of liquid level, thus achieve the goal of liquid level alarm, control and accident chain.
The characteristics of the liquid level of the magnetic flip plate
It is suitable for measuring the liquid level and the boundary position of pressure vessel.
The instruction is novel, the reading is intuitive and eye-catching. It can change the viewing Angle according to the user's convenience.
The measuring range is large, not restricted by storage tank.
The indicator is completely isolated from the measured media, so it is sealed, reliable and safe.
High temperature resistance, can be used in non-fading ceramic pillar.
Simple structure, convenient installation and low maintenance.
