side mounted M16 thread float level switch water tank plastic float switch sensor mercury mechanical float switch

This product is a simple structure, easy to use, safe and reliable liquid level control device, generally connected to relays or AC contactors. When the water level and oil level rise/drop to a certain distance, the induction switch will be closed or disconnected, and the relay/AC contactor will also be closed or disconnected to control the water pump, water level and oil level.

1. The reed switch does not require a separate power supply. 2. High reliability, low wiring cost and easy installation. 3. The specifications of the junction box are complete, including aluminum alloy, plastic, stainless steel and other materials. 4. The finished product is made of SUS304/316, which can be used in high temperature and high pressure places, and PP, PVC, PVDF plastic materials, which can be used in strong acid and alkali places. 5. The protection grade of the junction box is IP-65 or above.

The product is mainly composed of a reed switch and a float. There is a magnetic material in the float. When the float moves up and down with the liquid to be measured, the reed switch is triggered to detect the position of the liquid. The product can be used for water dispenser, water heater, solar energy, air conditioner, humidifier, bathroom equipment, vending machine, fuel tank, water tower, liquid level control of chemical liquid, anti-dry sensor for water heating equipment such as kitchen equipment and water heater.

1. The installation position should be far away from the water inlet, otherwise the float switch will cause errors due to the fluctuation of the water inlet. 2. The load of the controlled line must match the contact capacity of the float switch. 3. The specific gravity of the liquid to be tested must be greater than that of the float. 4. Please do not adjust the float position arbitrarily.

When the float switch is used in circuits with capacitive loads such as motors, relays, solenoid coils, capacitors, incandescent light bulbs, long cables, etc., a surge current will be generated between the contacts of the switch. The two ends of the float switch are connected in parallel to protect the circuit, such as: RC (buffer), varistor, diode, current limiting resistor, surge absorber, etc. Note: Do not connect the float switch directly to the solenoid valve, motor, etc.
