Diaphragm Type KF-500 Series

►Features
No power source is needed! Viscous liquids and high-temperature liquids can also be detected!
As the moving part design is simple, stable operations are ensured. A liquid in a tank contacts the detecting pipe but does not touch the main body of the switch. Even highly viscous and cohesive liquids as well as high-temperature liquids that are difficult to detect through a float switch can be measured with relative ease.

►Operating Principles

When the water level in the tank rises, the internal pressure of the detecting pipe increases and the diaphragm pushes the micro switch to produce contact output. When 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 weight of the diaphragm.
