VEGA EL 8 Conductive probe - Manual (Page 7)

Conductive probes detect the product resistance when their electro-
des are covered by the product.
The switching signal is determined by the length or mounting position
of the respective electrode.
A low alternating current flows through the electodes, is measured for
amplitude and phase position by the electronics of the signal
conditioning instrument and converted into a switching command.
EL 8 is operated with an external processing unit. The connected
signal conditioning instrument powers EL 8 and provides a switching
signal. A connected device can be activated directly with this switching
command (e.g. a warning system, a PLC, a pump, etc.).
You can find the exact range of the voltage supply in chapter
"T
echnical data" in the operating instructions manual of the signal
conditioning instrument.
3 .3 Operation
The probe does not have its own electronics. The measurement is
carried out via the connected signal conditioning instrument.
3 .4 Storage and transport
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE foil
is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or
concealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
l Not in the open
l Dry and dust free
l Not exposed to corrosive media
