3.2 Principle of operation
VEGACAL 63 is a level sensor with fully insulated probe for continu-
ous level measurement.
The electronics functions according to the admittance principle
(phase-selective admittance processing).
It is designed for industrial use in all areas of process technology and
can be applied in all areas of industrial process measurement.
Fully insulated probes such as VEGACAL 63 are preferably used in
conductive liquids.
Probe, measured product and vessel wall form an electrical capacitor.
The capacitance is influenced by three main factors.
