3.2 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
®
measuring cell with rug-
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
®
measuring cell is equipped with
a lateral, recessed seal.
