Capacitive level measurement 

The sensor and the wall of the container form the two electrodes of a capacitor. When the level changes, the electrical capacitance between the electrodes also changes. This change is evaluated by the electronics and converted into an output signal. Robust cable and rod versions cover a variety of applications.

The advantages

Fully insulated instrument versions also measure aggressive liquids or highly adhesive media.
Partly insulated versions perform reliable switching in powdered and granular bulk materials. The construction and quarrying industry, in particular, benefits from the sturdy build of these instruments.
