NOTE:
Distance to inner duct wall
The distance between internal duct wall and sender/receiver unit measuring opening
should be at least 100 mm. For the high-temperature version, the distance should be
between 100 mm and 140 mm so that the measuring device does not protrude too far
into the duct and is not warmed up unnecessarily by the hot sample gas.
