Mounting
Lockings
A locking is available for height adjustment on
the VEGASWING 83 A with screw connection.
This locking allows adjustment and modifica-
tion of the switching point after installation.
Bring the switching point of the tuning fork to
the requireded height. Lock the tube in this
position by tightening the pr essure scr ew.
Secure the pressure screw against loosening
with the fixing scr ew.
You can use VEGASWING 83 A in vessels
with up to 25 bar pressure. Use the locking
(G 1

“ NPT) up to 25 bar
(ARV2EX0.C…). Follow the operating instruc-
tions for the locking.
Lateral load
Ensure that the vibrating element is not sub-
jected to lateral forces. Mount the instrument
at a location in the vessels wher e no inter fer-
ing influences such as those caused by
stirrers, filling openings etc. can occur . This is
particularly important for instrument types
with cables or extension tubes (see fig. 2.5).
The surfaces of the tuning fork should be
parallel to the product movement, so that the
tuning fork of VEGASWING offers only little
resistance.
VEGASWING with enamel or ECTFE
Treat instruments with enamel or ECTFE-
coating very carefully and avoid shocks.
Unpack VEGASWING just before mounting.
Insert VEGASWING carefully into the vessel
opening provided and avoid contact with
sharp-edged vessel parts.
Flow
(e.g. in pipes)
When mounting in pipes or in vessels with
certain flow direction, you should mount
VEGASWING such that the surfaces of the
tuning fork follow the flow direction, see also
"Welded socket “.
