Power supply voltage: There are usually a variety of specifications to choose from, the common ones are AC 110V, AC 220V, AC 240V, etc., which can adapt to different power supply environments.
Rated current: generally 5A, which can meet the current demand of conventional control circuits.
Applicable liquids: It is suitable for controlling the liquid level of various conductive liquids, but cannot be used for volatile liquids.
Features: With the function of automatic control of the liquid level, the water level of the liquid container can be monitored and controlled, when the water level reaches the set upper or lower limit value, the relay will automatically act, and the relevant equipment will be controlled to add water or drain the operation to keep the water level within the appropriate range.
Protection characteristics: It usually has a surge protection function, which can effectively prevent surge interference in the power supply and protect the internal circuit of the relay from damage.
Electrode characteristics: The use of low AC voltage electrode head can avoid electrolysis, prolong the service life of the electrode head, and reduce the problem of electrode corrosion and liquid pollution caused by electrolysis.
Indication function: There are two indicator lights, which are used to display the water supply and drainage status, which is convenient for users to intuitively understand the working condition of the equipment, so as to find abnormalities and deal with them in time.
