Water Level Float Switch
Notice:
The float should be used with the relay. It cannot be connected directly to the power supply. Otherwise, the float may be short-circuited and burned out.
features:
1. 0-110V Side mounted automatic water level float switch, liquid level sensor, PP plastic probe switch, water tank filling switch.
2. A float switch is a device used to sense the level of liquid within a tank, it may actuate a pump, an indicator, an alarm, or other device.
3. Use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating, or what ever your project may be.
4. The float liquid level switch is a liquid level control device with simple structure and convenient use. It does not need to provide power supply, has no complicated circuit, and has the advantages of smaller volume and longer working life than general mechanical switches. As long as the material is selected correctly, and any liquid or pressure can be used, it can be used in the shipbuilding industry, generator equipment, petrochemical industry, food industry, water treatment equipment, dyeing and finishing industry, hydraulic machinery, etc. application.
5. Working principle:
The liquid level sensor is mainly composed of a reed switch and a floating ball. The floating ball has magnetic material. One or more reed switches are arranged in the closed non-magnetic metal tube or plastic tube, and then the catheter is passed through a Or a plurality of floating balls with magnetic material, and using the fixed double ring to control the floating ball and the reed switch in the relevant position, the floating ball rises or falls with the liquid, and uses the contact point in the ball near the beginning of the magnetic spring to generate opening and closing. The action is used as a level control or indication (when the float is close to the reed switch is on; when it is off the switch is off).
