NOTE:
Clearance to inner duct wall
The clearance between internal duct wall and sender/receiver unit measuring volume
should be at least 100 mm. For the high-temperature version, the clearance 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.
