Working Principle of a magnetic Float Sensor
The magnetic float sensor is partially submerged in the liquid,tracking the liquid surface motionprecisely.As the liquid level rises the float gets lifted,which slides the attraction sleeve up inside the enclosing tube and into the magnetic field to actuate the electrical or pneumatic switch.This signals the presence of the liquid.
Similarly,as the liquid level decreases the float gets lowered,which draws the sleeve out of themagnetic field and deactivates the electrical or pneumatic switch.This indicates the absence of the liquid.
As the working principle of the magnetic float sensor relies on the interaction between magnets,this device doesn't require a power source.They are also almost maintenance free and their magnetic force can affect optional switches or transmitters mounted outside of the chamber.
