Magnetic flap liquid level gauge with remote transmission signal signal output mode and installation requirements
The working principle of the magnetic flap level meter :
First of all, we need to understand the structure of the magnetic flap liquid level gauge: each magnetic flap liquid level gauge has a cavity containing a floating ball, called a main body tube or a shell, which forms a container with a container through a flange or other interface. The connector; so that the liquid level in the cavity is the same as the liquid level in the container, so the floating ball in the cavity will rise and fall as the liquid level in the container rises and lowers; a flip column display is installed outside the cavity Because we installed magnetic steel at the junction of the floated liquid and the floated part when manufacturing the float. When it and the float rise and fall with the liquid level, its magnetism is transmitted to the flip-column display through the shell, which pushes the magnet. The flip column is turned 180 °; because the magnetic flip column is a cylinder composed of two semi-cylindrical columns, red and white, the color will change after facing 180 ° and turned outside the flip column display. The junction of the two colors is the height of the liquid surface.
The flap box outside the main body of the magnetic flap liquid level gauge is affected by the float inside the body (with a directional magnetic source, which is developed according to different media and pressure) to urge its flip to flip and display red and white colors, and it varies with the movement of the float. Height of the liquid surface. On the left side of the indicator is equipped with a conspicuous scale, which makes the indication of the liquid level more clear. So, if the magnetic flap liquid level gauge has remote transmission, how can the signal be transmitted remotely? The magnetic flap level gauge with remote transmitter works in the transmitter part and the electrical part. The magnetic float acts on the magnetic reed switch to cause the change in the number of resistances connected to the circuit, which in turn makes the sensor part A resistance signal corresponding to the level change can occur. The remote signal transmission part is a signal converter composed of a built-in reed switch, which can convert the resistance signal into a current signal of 4-20mA. The electronic components of the magnetic level gauge are almost free of energy storage components such as capacitors and inductors. If required by the site, the communication protocol can also be superimposed, and bus communication can also be used.
The magnetic flap liquid level meter with remote transmission supporting instruments needs to do the following:
1. The remote transmission supporting instrument should be close to the main pipe of the level gauge and fixed with stainless steel hoop (iron is prohibited). 2. The sensing surface on the remote transmission supporting instrument should face and close to the main conduit; 3. the remote transmission supporting instrument The zero position should be on the same horizontal line as the zero indicator of the level gauge; 4. The connection between the remote transmission supporting instrument and the display instrument or the industrial computer should be laid separately through a protective tube or a shielded two-core cable; 5. After laying the wire entry hole of the junction box, it is required to be well sealed to prevent rainwater, moisture and other intrusions and prevent remote transmission supporting instruments from working properly. The junction box should be covered in time after the maintenance or commissioning is completed.
