Note the following if the antenna does not project out of the nozzle:
• The end of the nozzle must be smooth and free from burrs. The edge of the nozzle should be
rounded if possible.
• Mapping must be performed.
• Please contact Hauser for applications with nozzles that are higher than indicated in
the table.
Mounting cladded flanges
Note the following for cladded flanges:
• Use the same number of flange screws as the number of flange bores provided.
• Tighten the screws with the necessary torque (see Table).
• Retighten after 24 hours or after the first temperature cycle.
• Depending on the process pressure and temperature, check and retighten the screws, where
necessary, at regular intervals.
The PTFE flange cladding normally acts simultaneously as a seal between the nozzle and the
device flange.
