Water level indicatorL3-S (see Figure 1) for side-loading water level sensor. duckbill tongue designed, one of our hot sell products. Through a stainless mold injection molding parts connect , simple structure, easy to use, safe and reliable for the level control device, To compare with normal electronical switch , it has a smaller volume response more quickly speed, more long life and stronger anti load impact .The float switch structure is simple,without complex circuit ,will not be disturbed,easily use to control level components,as long as the material selection is correct, it can application in any liquid with any pressure and temperature environment.
A: The components.
1: The main stem material: SUS304/316
2. The float material:SUS304/316
3. Assembly: Reed switch magnet Epoxy
4. Lead Wire.30 cm.
B: Working principle:
The side-mounted float level electrical switch is to use liquid buoyancy principle, along with the liquid level ,the duckbill float will move up and down,
then it will trigger the reed switch that sealed in the junction box ,the magnet arm will be affected, and sending the connect (ON) or disconnect (OFF) signal.
C:The installation instructions (see Figure II)
1.on the both sides tank,side mount, No( open) or NC (closed) by reversing 180 degrees.
2.the diameter of the connector thread is 1/2 “ NPT, hex-head height is 5mm, duckbill(float ball body ) length is 91 mm.
3. Directly install at the side of the tank.
1: The range of temperature -30 ~ 135 C
