2.1 Installation instructions
Lateral load
Make sure that the measuring cable is not
subjected to strong lateral forces. Mount
VEGAFLEX to a position in the vessel where
no interfering influences from e.g. stirrers,
filling openings etc., can occur.
Lateral load
Extraction forces
In case of strong extraction forces, e.g. dur-
ing quick emptying or settling of solids, high
tensile loads can occur.
When such an installation position is neces-
sary, the cable should not be anchored but
only equipped with a gravity weight, so that
the cable can more easily follow the product
movements.
Make sure that the vessel top can support
the max. tensile load.
Pressure
In case of gauge or low pressure in the ves-
sel, the mounting boss should be sealed on
the thread. Use the attached seal ring. Check
if the seal ring is resistant against the con-
tained medium.
Shortening the measuring cable
The cable can be shortened later as re-
quired. Loosen the three set screws on the
gravity weight (hexagon) and remove them.
Pull the cable out of the gravity weight.
To avoid fraying the steel cable during cut-
ting, you have to tin the cable around the
cutting position with a soldering iron or torch,
or wrap the cable tightly with wire or insulat-
ing tape. Shorten the cable with a metal cut-
ting saw or a cutting wheel to the desired
length.
In case of insulated cables with gravity
weight, a certain length of insulation should
be removed (VEGAFLEX 51: 45 mm; VE-
GAFLEX 52: 60 mm). In cable loops, the
insulation must remain on the cable.
After shortening, reinsert the cable (see "4.2
Adjustment with adjustment module MINI-
COM").
