Mounting with a compression fitting
The sensor is installed using a special compression fitting. Normally, a
sleeve is welded as a connecting piece onto a bore in the medium-
guiding pipe, in which the external thread (G½) of the compression fitting
is screwed (see Figure 3).

Bore a mounting opening in a pipe wall.
Weld connecting piece with an internal thread G½ in the center
above the mounting opening on the pipe.
Recommended length of connecting piece: 15 ... 40 mm
If necessary wrap thread using a common sealing tape, for example
made of PTFE.
Screw threaded part of compression fitting one or two turns by hand
into connecting piece then tighten it with a screw wrench (SW27).
Remove compression fitting nut and extract both poetry halves.
Remove protective cap from sensor tip and attach compression fit-
ting nut on sensor probe.
Insert probe in threaded part of the compression fitting, attach poetry
halves and screw on fitting nut manually to such an extent that sen-
sor probe can be inserted without jamming.
