3.6 Installation notes on the individual device classes
3.6.1 Threaded compact sensor
A threaded compact sensor can be installed two different ways:
• Screwed in directly: Pipes with a wall thickness ≥ 20 mm / 0.8" make it possible to drill a hole
and cut a thread.
• Screw into threaded sleeves: Pipes with a wall thickness < 20 mm / 0.8" require a sleeve to be
welded in; these are not included in delivery but make up part of the accessories range.

CAUTION!
You, the user, are responsible for selecting a suitable sealing material for the process
connection, not the manufacturer! When installing the seals to the process connection, always
ensure a good fit!
CAUTION!
Sometimes even a neck tube cannot prevent the maximum permissible temperature in the
connection head from being exceeded! It does cause extensive thermal decoupling of the
connection head but you still have to always take into consideration the installation situation as
well as the ambient and process temperatures!
