Capacitive electrodes EK with signal conditioning instrument 5
Product description
The floating signal of the electrode electronics
is in the range 4 … 20 mA and can be there-
fore connected without additional potential
separation to other processing systems such
as e.g. VEGALOG.
In addition to the continuous measurement,
also levels can be detected (VEGAMET or
VEGAMET + VEGASEL).
Level detection
Level switches should signal when certain
levels are reached, e.g. max. or min. levels.
These levels are detected at a fixed point
and converted into a switching command.
For level detection capacitive electrodes EK
with appropriate signal conditioning instru-
ments VEGATOR are available. A switching
command can be either triggered when the
electrode is covered or uncovered.
