Background

The float switch is a liquid level control part with simple structure and convenient use, is provided with a complex circuit, cannot be interfered, and can be used for liquid, pressure and temperature with any property as long as the material is selected correctly. Float switch theory of operation: usually, a one-point or multi-point magnetic reed switch (dry pipe) is arranged in a sealed non-magnetic metal or plastic pipe according to requirements, then a hollow floating ball with an annular magnet inside is fixed at a relevant position of a magnetic switch in the diameter of a rod, so that the floating ball floats up and down in a certain range, the magnet in the floating ball is used for attracting the closing of the magnetic reed switch to generate switching action, and the floating ball switch plays a role in controlling and sensing the water level and the liquid level.

The current field uses the cable float switch, when the liquid level rises to drive the float ball, the float ball uses the weight as the center to do angle change along with the rising of the water level, when the angle between the horizontal plane and the rising line exceeds 28 degrees, the steel ball of the float ball moves with the angle to generate ON or OFF contact signal output. The concentration of the on-site slime water changes frequently, so that the phenomenon that the pump cannot be started or stopped when the rising angle of the floating ball reaches the action condition often occurs, and further the phenomenon that a pump pit is submerged or the pump idles for a long time occurs.
