conductive"Monitor filing levels quickly and reliably."

Baumer conductive filling level switches detect conductive liquids quickly, reliably and to the millimeter at up to four switching points.
They are robust, extremely resistant and so are particularly ideal for filling level measurement and dry running protection for pumps. In a compact, hygiene rules compliant design with 3A certification, these are used around the world in the food and beverage processing industry.

The sensor we use can withstand temperatures from –20 to 140 °C and is therefore also suitable for CIP and SIP processes. 
As the measuring rod can be shortened to any length needed, every installation becomes extremely simple.


LSK also enables measuring the filling levels in containers where they can only be installed from above. The measuring rod is available up to 2m long, and so also suitable for deep tanks. For containers made of non-conductive materials the measuring stick can be used to ground.
