Mounting instructions

Welding socket
For threaded versions of VEGASWING S 52 in
combination with a mounting boss with O-ring in
front and welding marking.
VEGASWING S 52 with thread sizes ¾" and 1"
have a defined thread runout. This means that
every VEGASWING S 52 is in the same position
after being screwed in. Remove therefore the
supplied flat seal from the thread of VEGAS-
WING S 52. This flat seal is not required when
using a welded socket with front-flush seal.
Before welding, unscrew VEGASWING S 52
and remove the rubber ring from the welded
socket.
The welded socket is provided with a marking
(notch). For horizontal mounting, weld the so-
cket with the notch facing upward or downward;
in pipelines (DN 25 to DN 50) aligned with the
direction of flow.

1 Marking
Adhesive products
In case of horizontal mounting in adhesive and
viscous products, the surfaces of the tuning fork
should be vertical. The position of the tuning
fork is indicated by a marking on the hexagon of
VEGASWING S 52. With this, you can check the
position of the tuning fork when mounting it.
In case of horizontal mounting in adhesive
and viscous products, the tuning fork should
protrude into the vessel to avoid buildup on the
tuning fork.
Flows
To make sure the tuning fork of VEGASWING
S 52 generates as little resistance as possible
to product flow, mount the sensor so that the
surfaces are parallel to the product movement.

Contactless electronic switch
The instrument is used for direct control of
relays, contactors, magnet valves, warning
lights, horns etc. It must not be operated without
intermediately connected load, because the
electronic would be destroyed if connected
directly to mains. It is not suitable for connection
to low voltage PLC inputs. Domestic current is
temporarily lowered below 1 mA after switching
off the load so that contactors, whose holding
1
current is lower than the constant domestic
current of the electronics (3 mA), are reliably
switched off.
Examples for typical applications:

For the plug version valve plug ISO 4400, stan-
dard cable with round wire cross-section can be
used. Cable diameter 4.5 ... 7 mm, protection
IP 65.
