Point level measurement with capacitive level switches
Sensor and vessel form the two electrodes of a capacitor. When the level changes, the capacitance between the electrodes also changes. The sensor electronics determines via the capacitance when the defined limit has been reached. The capacitive measuring principle is a robust technique for use in applications where heavy buildup makes measurement difficult.
The advantages
Fully insulated instrument versions also measure aggressive liquids or highly adhesive media.
Partly insulated versions perform reliable switching in powdery and granular bulk materials. The construction and quarrying industry, in particular, benefits from the sturdy build of these instruments.
