In the domestic water system, the control of the water tank loading and unloading is an important link. Traditional methods usually use float switches to achieve water level control, but traditional float switches have some obvious drawbacks, such as easy to jam, short life and poor reliability. With the continuous development of science and technology, small float level switches have gradually entered people's field of vision, and are widely used in household water tank water control.
The small float level switch is a liquid level sensor based on the buoyancy principle, which controls the on/off of the circuit by sensing the change of liquid level. In the domestic water tank water tank water control, the function of the small float level switch is to detect the water level of the water tank, and control the start and stop of the water pump according to the set water level height. When the water level reaches the set height, the float rises, the contacts are closed, and the pump starts; When the water level is below the set height, the float is lowered, the contacts are disconnected, and the pump stops. In this way, the water level of the water tank can be accurately controlled, and the phenomenon of water overflow or empty pumping of the pump can be avoided.
Compared with traditional float switches, small float level switches have the following advantages:
1.The structure is simple, the size is small, and the installation is convenient.
2.Wear-resistant materials are used to make floats, which have long life and high reliability.
3.The contacts are made of materials with excellent electrical conductivity, low contact resistance, and strong current passing ability.
4.The sensing height can be adjusted to meet the needs of different water levels.
Through the reasonable selection and correct installation of small float level switches, the stability and reliability of household water systems can be effectively improved, bringing convenience and comfort to people's lives.
