The working principle of the float type liquid level switch is based on the magnetic float rising and falling with the liquid level, and the switch signal is sent out through the built-in reed switch. When the liquid level rises or falls, the float moves accordingly, driving the magnetic system inside the reed switch to act, thereby triggering the closure or disconnection of the switch, achieving liquid level control.
The main components of a float type liquid level switch include a magnetic float and a reed switch. Floats are usually made of plastic or stainless steel, while reed switches are placed inside non-magnetic tubes. When the liquid level changes, the float moves, causing the reed switch to close or disconnect, and outputting the corresponding switch signal. This working principle makes the float type liquid level switch suitable for liquid level measurement in various industrial conditions, with features such as simple structure and strong reliability.
