VEGACAP 64 • Two-wire
30015-EN-230510
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
4.2 Mounting instructions
Due to the effects of agitators, equipment vibration or similar, the level
switch can be subjected to strong lateral forces. For this reason, do
not use an overly long electrode for VEGACAP 64, but check if you
can mount a short level switch on the side of the vessel in horizontal
position.
Extreme vibration caused by the system, e.g. due to agitators or
turbulence in the vessel from fluidisation, can cause the probe of
VEGACAP 64 to vibrate in resonance. If a longer rod version is neces-
sary, you can secure the probe by fastening a suitable brace or guy
directly above the end of the rod.
If the instrument is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount the
instrument at a position in the vessel where no disturbances, e.g. from
filling openings, agitators, etc., can occur.
This applies particularly to instrument versions with a longer probe.

To achieve a very precise switching point, you can install VEGACAP
64 horizontally. However, if the switching point can have a tolerance
of a few centimeters, we recommend mounting VEGACAP 64 approx.
20° inclined to the vessel bottom to avoid buildup.
Install rod probes in such a way that the probe projects freely into the
vessel. When the instrument is mounted in a tube or nozzle, buildup
can form which impairs the measurement. This applies mainly to
adhesive products.
