VEGA VEGAKON 61 - Transistor (NPN_PNP) - Manual (Page 7)

When the annular electrode is covered with a conductive medium,
small alternating currents (<1 mA) flow from the measuring electrode
to the reference and neutralisation electrode.

These alternating currents are measured in respect to their amplitude
and phase position and converted into a switching command.
Interfering buildup is automatically eliminated via the neutralisation
electrode, the conductivity detected and the switching point sensitivity
derived thereof. An adjustment of the instrument is not necessary.
VEGAKON 61 can be used for reliable detection of products over a
very wide conductivity and viscosity range.
VEGAKON 61 is a compact instrument, i.e. it can be operated without
external evaluation system. The integrated electronics evaluates the
level signal and outputs a switching signal. With this switching signal, a
connected device can be operated directly (e.g. a warning system, a
PLC, a pump etc.).
The data for power supply are specified in chapter "Technical data".
3 .3 Operation
The VEGAKON 61 is a compact level switch with integrated
electronics module.
On the electronics module you will find the following indicating and
adjustment elements:
l Control lamp for indication of the switching status
l Mode changeover for selection of the output signal
