4.2 Mounting instructions
OPTISWITCH 5100 C, 5150 C has a defined thread starting
point. This means that every OPTISWITCH 5100 C, 5150 C is
in the same fork position after being screwed in. Remove
therefore the supplied seal from the thread of OPTISWITCH
5100 C, 5150 C. This seal is not required when using a welded
socket with O-ring in front.
Keep in mind that this welded socket is not suitable for coated
instrument versions.
Screw OPTISWITCH 5100 C, 5150 C completely into the
welded socket. The later position can be determined already
before welding. Mark the appropriate position of the welded
socket. Before welding, unscrew OPTISWITCH 5100 C, 5150
C and remove the rubber ring from the welded socket. The
welded socket has a marking (notch). Weld the socket with the
notch facing upward, or in case of pipelines, aligned with the
direction of flow.

1 Marking
In case of horizontal mounting in adhesive and viscous
products, the surfaces of the tuning fork should be vertical in
order to reduce buildup on the tuning fork. On the screwed
version you will find a marking on the hexagon. With this, you
can check the position of the tuning fork when screwing it in.
When the hexagon touches the seal, the thread can still be
turned by approx. half a turn. This is sufficient to reach the
recommended installation position.
With flange versions, the fork is directed to the flange holes.
