Characteristics: It is polished, and the appearance is beautiful.
The magnetic unit material is NdFeB which is used in Space station, the magnetic structure is special,
so the magnetic beam is centered in the line plan, the strength can be sustained.
The output contact is with magnetic memory. Installation of insert mode, easy to maintain. Operation without electricity. Matching with photo-electric sign, apply to the condition of dusky light.
Profile
MN magnetic flap level meters adopt side mounting through a bypass pipe which is characterized by its easy installation, high stability and reliability or top mounting through a guide rod. The level meter is completely isolated between the inside and outsider cavity, and added a sealed flange at its bottom which can be opened easily to clean up dirt, impunity, etc.. One way level meters and meters adopting top mounting for its guide rod , equipped with a pressure hole in the top connected with atmosphere, are suitable for measuring level of medium at room temperature and pressure; Two-way level meters can be made with a certain operating pressure according to customers' needs, and are suitable for measuring the liquid level of corrosive medium in places with high temperature, high humidity and high pressure. Level meters mainly consist of body of magnetic flat, display board of magnetic flat, floating ball, magnetic memory switch, ruler, etc.. In addition, an transmitter can be added according to customers' needs.
Side mounted magnetic bundle unit through a bypass pipe is placed inside of the floating ball, while top mounted magnetic bundle unit is connected with a floating ball. When the floating ball moves over liquid level, the magnetic bundle unit shall move along a level relay made up of a serial of magnetic module. Under the action of the magnetic unit, the magnetic module inside the level sensor shall make a corresponding action, output a changed resistor signal, and then transfer the signal into a current output signal of 4~20mA. Meanwhile, the level can be observed directly through the quartz tube, and a magnetic switch shall conduct a related action at the corresponding point, making alarming action and control output.
