Electrode type liquid level switch

First, the working principle

Electrode level switch uses the conductivity of liquid to detect the level of liquid. Once the material inside the barrel touches the pole, it conducts electricity and thus detects the signal. After the signal of the controller is amplified, a contact signal is output for the user to control the liquid level.

Second, product characteristics

1, suitable for controlling the liquid level of any conductive liquid. (Do not use on volatile liquids)

2, with sudden wave protection function, can effectively prevent the sudden wave interference

3, can do multi-point control, the control position can be customized by the user

4, Electrode head using low AC voltage, can avoid electrolysis, and can prolong the service life

5, With two indicator lights, can show the water supply and drainage status

Three, matters needing attention

1, only for vertical installation

2, the voltage fluctuation range is within ±15%, the voltage should be stable

3, avoid installation in the place of large vibration or impact (may lead to misoperation)

4, non-conductive liquid is not suitable for this product, such as: gasoline, diesel oil, heavy oil,

Pure water, etc.

5. All the poles should be at least 50mm apart from the longest pole

6, when the liquid comes into contact with the electrode, its action will be changed due to the different types of liquid and the change of power supply voltage.

7. In order to ensure that the electrode rods will not contact each other in water, tape can be wrapped on the pole, but it must be wrapped on the part after 100mm of the front end of the pole.
