Do not hold OPTISWITCH 5200 C, 5250 C on the tuning fork.
Particularly with flange or tube versions, the tuning fork can be
damaged by the instrument weight. Transport enamelled and
ECTFE coated instruments very carefully and avoid touching
the tuning fork.
Remove the protective cover just before mounting.
The process fitting must be sealed if there is gauge or low
pressure in the vessel. Before use, check if the seal material is
resistant against the measured product and the process
temperature.
The vibrating level switch is a measuring instrument and must
be treated accordingly. Bending the vibrating element will
destroy the instrument.
Warning:
The housing must not be used to screw the instrument in!
Applying tightening force to the housing can damage its
internal mechanical components.
To screw in, use the hexagon above the thread.

4.2 Mounting information

OPTISWITCH 5200 C, 5250 C has a defined thread starting
point. This means that every OPTISWITCH 5200 C, 5250 C is
in the same fork position after being screwed in. Remove
therefore the supplied seal from the thread of OPTISWITCH
5200 C, 5250 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 (e.g. enamel).
Screw OPTISWITCH 5200 C, 5250 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 5200 C, 5250
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.
