VEGAKON

Proven compact limit switches

Measuring principle and applications

The instruments work according to the conductive measuring principle

and are used in conductive liquids. A low alternating current owswhen the probe is covered by the medium which is detected by the

integrated electronics and converted into a switching command. The

switching point is determined through the mounting position or the

length of the respective probe. The easy and robust construction of

the sensors offers a maintenance-free and reliable level detection in

all areas of industrial measurement technique. Typical applications

are overll protection, pump control or dry run protection in vessels or

pipelines.

Conductive probes EL

Flexible level detection

Measuring principle and applications

The instruments are used for level detection in conductive liquids. For

operation of the conducitve probe, a VEGATOR 256 C or 632 signal

conditioning instrument is required. When the electrode is immersed,

a low alternating current ows which is detetcted by the VEGATOR

signal conditioning instrument, processed and converted into a

respective switching command. The switching point is determined

through the mounting position or the length of the respective probe.

The easy and robust construction of the sensors offers a maintenance-

free and reliable level detection in all areas of industrial measurement

technique. Typical applications are overll protection, pump control or

dry run protection in vessels and pipelines.
