Diaphragm Type Level Switch KF-500 Series

No power source is required! Viscous and high temperature liquid is detectable!

Features

Simply designed moving part ensures its stable operation
Liquid in a tank contacts the detecting pipe but does not touch the main body of the switch
Highly viscous and cohesive liquid as well as high-temperature liquid, which is difficult for the float switch to detect, can be detected

Operating Principles

As the water level in the tank rises, the internal pressure of the detecting pipe increases and the diaphragm pushes the micro switch to make contact output. As the water level falls and the internal pressure of the detecting pipe decreases, the contact output is released by the return force of the micro switch and the deadweight of the diaphragm.
