The float switch is a special switch because it does not require power supply. It is a very simple pressure switch. It is small in size and made of stainless steel or plastic. It has a long working life. Water treatment has been widely used.
The power of the float switch is magnetic and does not require additional mechanical connections. Its structure is a float, body and magnet. When the object to be measured of the float switch floats on the float, the float will start to move under the influence of buoyancy, and the main body will move up. At this time, the magnet at the other end will control the switching action of the main rod. This is the float. The general working principle of the switch.
The advantage of the float switch is that it can accurately measure the water level of the liquid, so it is generally used in the liquid detection of atmospheric or pressurized liquid storage tanks, for the signal transmission, such as liquid level alarm, the applicability is very Strong. It can accept multi-point control, and its location can also be determined by the customer. It does not require a power supply to ensure its environmental friendliness. Its life expectancy is about 2 million times of switching, high cost performance and high protection level. It can work under high temperature or high pressure conditions and has high safety.
