VEGA Float for oil_water detection for for VEGACAP 63 - Manual (Page 6)

The probe detects non-conductive light liquids (< 1 kg/dm³) on water,
e.g. in water or oil separating basins.

The measuring system floats on the water and due to the own weight
the electrode of the probe immerses up to a certain depth.
If there is e.g. oil on the water surface, the measuring system floats.
The immersion depth of the electrode in water reduces. Hence the
capacitance of the probe changes. The capacitance change is
converted into a switching command.
An oil layer can be already detected from a thickness of 4 mm.
3 .3 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.
