Principle of operation

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.
The CERTEC measuring cell is also equipped with a temperature
®
sensor Pt 100 in four-wire technology. The resistance value is ac-
cessed via the wires of the suspension cable. The power supply or the
processing is carried out via an external temperature transducer.
As a standard feature, the CERTEC
