Purpose:
It is specially used for liquid level detection of various medium and small normal pressure and pressure liquid storage tanks, remote transmission of on-site indication signals, and liquid level alarm. It can be applied to various sanitary, toxic, corrosive media and explosive gas dangerous places. There are a variety of installation forms, suitable for various forms of containers.
Customers who use water purifiers recommend buying high-voltage ones, because the circuit board load of the water purifier exceeds the current withstand the low-voltage contacts. The high-voltage ones have a large contact capacity, and the high-voltage ones are not easy to break.
1Note: Low voltage means that the float switch can be used on the line of DC 0~110V
High voltage means that the float switch can be used on AC 0~220V, DC 0~200V lines
2 Note: The rated current of the contact is 0.5A. Pay attention to it. Generally, it should be used in conjunction with a small relay. Overcurrent will burn the contact. It cannot directly control AC contactors, solenoid valves, alarms, water pumps, and various lights.
2This is without a screw cap. Please pay attention when purchasing. Please purchase the other 3 specifications for perforated installation of the water tank.
