The KOBOLD level switches RFS are designed for monitoring filling levels of liquids cost-effectively. The liquid must not contain solids nor metallic particles. A pivoted stainless steel float with an inserted solenoid moves up and down together with the filling level of the liquid.
The solenoid switches a reed contact. Depending on the mounting position of the device, the contact works as N/O or N/C contact with rising filling level. The devices are delivered for direct lateral mounting in commercially available sleeves.
