10 PREPARATION FOR INSTALLATION
Select the optimal sampling point in accordance with the generally applicable guidelines or consult the
competent persons.
Locate the sampling point in such a way that there is adequate space for inserting and removing the
probe and pay attention to the insertion length of the probe tube.
Make certain that the probe is easily accessible so that you can carry out any subsequent
maintenance work without trouble.
If the ambient temperature in the area of the connections is >70°C as a result of radiated heat, then a
radiated-heat deflector must be mounted to protect the probe.
The connection's mounting flange connection should comply with DN65 PN6. If other connection sizes
are required, the stud bolts of the heated sample tube can be arranged accordingly as option.
The necessary minimum flange size and the minimum connection diameter depends on the diameter
of the probe tube or pre filter used.
Before mounting, the probe must be adjusted to the existing operating conditions.
The existing operational parameters are to be checked accordingly prior to commencing mounting
work (see also technical data, chapter 9):
