Mounting
Lateral load
Shortening of the measuring cable
Extraction forces
In case of strong extraction forces, e.g. due
to quick emptying or material sliding, high
tensile loads can be caused. Should such a
mounting position be necessary, the cable
should not be fixed, but provided instead
with a gravity weight so that the cable can
more easily follow the product movements.
Make sure that the cable does not touch the
vessel wall.
Pressure
In case of gauge or low pressure in the ves-
sel, the mounting boss must be sealed on the
thread. Use the supplied seal ring. Make
sure that the seal ring is resistant to the me-
dium.

2.1 Installation instructions
Lateral load
Make sure that the cable is not subjected to
strong lateral forces. Mount VEGAFLEX at a
position where no interfering influences such
as by stirrers, filling inlets etc. can occur.
Shortening of the measuring cable
The cable can be shortened any time later.
Loosen the three headless screws (hexagon)
on the gravity weight and remove them. Pull
the cable out of the gravity weight.
To prevent the steel cable from unraveling
after cutting, you should tin-plate the cable at
the cutting position with a soldering iron or
flame or strongly bind the cable with a wire.
Shorten the cable by the requested length
with a hacksaw or a cutting-off wheel.
In case of insulated cables with gravity
weight, the insulation should be removed
over a length of 45 mm.
Cable entries
When mounting outdoors, on cooled vessels
or in humid areas where cleaning is done,
e.g. with steam or high pressure, the seal of
the electrical cable entry is very important.
Use electrical cable with a round cross-sec-
tion and tighten the cable entry firmly. The
cable entry is suitable for cable diameters of
5 mm to 9 mm.
