Electrode type level switch

Electrode level switch uses the conductivity of liquid to detect the liquid level. Once the conductive liquid in the tank touches the electrode rod, a signal will be detected and be amplified through controller, then output contact signal which is used to control the liquid level. Be applicable for industry of food, medicine, chemical, electronics, ships and water treatment.

Product Description

Product feature
● Suitable for controlling the level of the conductive liquids.( Not suitable to service the volatile liquids)
● With surge protection function, can effectively prevent surge interference
● Can do multi-point control, control position is customized according to application requirement
● The electrode head uses low AC voltage, which can avoid electrolytic action and prolong the service life
● With two indicators, can display water supply and drainage status

 

Usage attentions
● Electrode type level switch is only for vertical mounting.
● Voltage shall be stable, voltage fluctuation should be within ±5%.
● Do not install Electrode type level switch in the place where there is large vibration or impact, otherwise the controller maybe happen miss-action.
● Electrode type level switch is not suitable for Nonconductive liquid, such as Gasoline, diesel oil, heavy oil, pure water, etc.
● All detect rods must be at least 50mm away from the longest rod ( see the following diagram)
etls 01 installation
● When the liquid contact the electrode, the position of co-action will vary depending on the type of liquid and the voltage’s changing of the power supply.
● In order to ensure that the electrodes do not contact each other in water, an insulating sleeve can be added to the electrode rod.
● In order to avoid the torsional contact short circuit caused by the too long electrode rod, the standard length of the electrode rod with diameter 6mm shall be not more than 2m.
● This product’s operation temperature is -20℃-70℃ in the steam environment, and ≤200℃ in the non-steam environment.
