Principle of operation

Model VEGAWELL 52 is suitable for continuous level measurement of
liquids. Typical applications are measurements in water/waste water
facilities, deep wells and in the shipbuilding industry.
The actual sensor element is the CERTEC
ged ceramic diaphragm. The hydrostatic pressure causes a capaci-
tance change in the measuring cell via the ceramic diaphragm. This
change is converted into an appropriate output signal.
As a standard feature, the CERTEC
a lateral, recessed seal.
