  • Page 13 "Technical data" meets the existing ambient conditions. Fig. 6: Measures against moisture ingress Caution: Transport Do not hold OPTISWITCH 5200 C, 5250 C on the tuning fork. Particu- larly with flange or tube versions, the tuning fork can be damaged just by the weight of the instrument. Transport coated instruments very carefully and avoid touching the tuning fork.

  • Page 14: Mounting Instructions

    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.
  • Page 15 Inflowing medium If OPTISWITCH 5200 C, 5250 C is mounted in the filling stream, un- wanted false measurement signals can be generated. For this reason, mount OPTISWITCH 5200 C, 5250 C at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur. This applies particularly to instrument types with long extension tube. Fig. 8: Inflowing medium Product flow...
  • Page 16 For this reason, do not use an overly long extension tube for OPTISWITCH 5200 C, 5250 C, but check if you can mount a level switch on the side of the vessel in horizontal position.
