3.2 Principle of operation
VEGACAP 64 is a level switch with fully insulated, capacitive elec-
trode with active screen segment and active tip for level detection.
VEGACAP 64 is very rugged and maintenance-free and can be used
in all areas of industrial process technology.
Typical applications are overfill and dry run protection.
Fully insulated probes with screen segment like VEGACAP 64 are
preferably used in conductive, very adhesive liquids.
Due to the mechanical constructions of the active screen segment
and the active tip, buildup on the probe can be compensated.
The capacitive measuring principle places no special requirements
on installation. Hence, many different applications can be equipped
with VEGACAP 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.
