Product description

1 Product description

1.1 Function and configuration

The conductive measuring principle is used

for level detection of conductive liquids.

Function

When the probe (s) is covered by the

medium, conductive electrodes detect the

product resistance.

A low alternating current flows which is

measured by the electronics of the signal

conditioning instrument on amplitude and

phase position and converted into a

switching command.

The switching signal is determined by the

length or the mounting position of the

appropriate electrode (s).

Configuration

One or two conductive electrodes and a

signal conditioning instrument VEGATOR

256C, 532 Ex or 631 Ex are required to

implement a measuring system.
