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.
Applications in liquids
Mainly fully insulated instrument versions are used in these applications. Hence level detections of corrosive liquids or adhesive products are no problem. The mounting of the instruments is easy and the rugged construction is the basis for an interference and maintenance free operation.
Applications in bulk solids
Partly insulated versions are preferably used in bulk solids. Also here, we have the proven, rugged configuration as basis for the manifold and reliable use, e.g. in the aggregates and mining industry.
