Mounting
Lockings
For VEGASWING 83A EXD with screw con-
nection, a locking is available for height ad-
justment. With this locking it is possible to
adjust and modify the switch point after in-
stallation.
Bring the switch point of the tuning fork to the
requested height. By tightening the pressure
screw, you lock the tube in this position.
Secure the pressure screw with the fixing
screw against loosening.
You can use VEGASWING 83A EXD in ves-
sels with up to 25 bar pressure. Use the
locking (G 1

“ NPT) up to 25 bar
(ARV2EX0.C…). Note the operating instruc-
tions of the locking.
Lateral load
Note that the vibrating element is not sub-
jected to lateral forces. Mount the instrument
on a position in the vessels wher e no inter fer-
ing influences such as e.g. by stirrers, filling
openings etc. can occur . This is mainly due
for instrument types with cable or extension
tube (see fig. 2.5). The surfaces of the tuning
fork should be in parallel to the product
movement, so that the tuning fork of VEGAS-
WING only offers 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 pro-
vided vessel opening and avoid contact with
sharp-edged vessel parts.
Flow
(e.g. in tubes)
When mounting in tubes or in vessels with
certain flow direction, you should mount
VEGASWING such that the surfaces of the
tuning fork are along with the flow direction,
see also Welded socket .
