4.1.2
Selecting the flange with tube
The selection of a suitable flange with tube depends on the wall and insulation thickness of
the duct wall, the nominal length of the selected sender/receiver unit and the sample gas
temperature. Flanges with tube are available which are delivered with a 3.1 material
certificate (
see “Flange with tube”, page 122
). The material pairing of the duct and the tube
should also be taken into account when a welded connection between the flange with tube
and duct is planned.

Selecting the MCUDH Ex-3K control unit
Selection of the MCUDH Ex-3K control unit depends on the required power supply unit and
the optional field bus module (
). The control units are suitable for
operation in Ex-zones 2/22.
