Area of application
The conductive point level sensors of the VEGAKON series are used in
conductive liquids as overfill protection, pump control or dry run protection in
vessels and pipelines.
Measuring principle
When the electrodes of the sensor come in contact with a conductive liquid,
a small alternating current begins to flow. The electronics responds by
triggering a switching command.
Advantages
The simple, robust mechanical construction of the sensors ensures
maintenance-free, cost-effective and reliable point level detection in all areas
of industrial instrumentation. The sensors, which can be installed in any po-
sition, provide a direct switching output. All measuring instruments offer teh
possibility of detection serveral switching points in a vessel. The VEGAKON
sensors are designed as compact level switches, while the EL probes are
designed to be used in combination with signal conditioning instruments of
the VEGATOR series.
