3.2 Principle of operation
VEGACAL 64 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 64 are preferably used in
conductive liquids.
Fully insulated probes like VEGACAL 64 are preferably used in con-
ductive, very adhesive liquids.
The capacitive measuring principle places no special requirements
on installation. Hence, many different applications can be equipped
with VEGACAL 64.
The instrument can also be used problem-free in corrosive products.
Probe, measured product and vessel wall form an electrical capacitor.
The capacitance is influenced by three main factors.
