2.1 Mounting instructions

General

Generally, the instrument can be mounted in
any desired orientation. The instrument must
simply be mounted such that the electrode is
at the height of the requested switching point.
Various mediums and measurement specifi-
cations require different types of installation.
Hence, some instructions should be noted.

Length of the electrode

Note at the time of ordering electrodes for
vertical installation, that the electrode must be
immersed to the requested level according to
the electrical properties of the medium.

Note that the switching point of vertically
installed, adjustment-free electrodes (VE-
GACAP 27, 35, 98) can vary in the range of
the active part.

Lateral load

Make sure that the electrode is not subjected
to strong lateral forces. Mount VEGACAP at a
position in the vessel where no interferences
such as from e.g. stirrers, filling openings
etc. can occur (see fig. 2.1).

Plate electrode

Install the plate electrode (VEGACAP 82, 92)
such that the electrode is flush to the vessel
wall. The wall thickness of the vessel should
not exceed 20 mm. Chamfer the inner edge
of the hole so that build-up can be avoided.

Shortening of the electrode

Rod electrodes

Fully insulated electrodes have fixed dimen-
sions and thus must not be modified in their
dimensions. Any modification will destroy the
instrument.

All partly insulated electrodes can be short-
ened, see 5.5 Shortening of the electrode.
The measuring probes are compensated to
the respective electrode length with the fac-
tory setting. If the electrode is to be short-
ened by more than 30 %, you should
recompensate the electrode. Call our service
department.

Cable electrodes

The cable electrodes VEGACAP 31, 33, 34
and 35 can be shortened afterwards (see fig.
2.2). See 5.5 Shortening of the electrode.
