First make sure that conditions at the intended place of use correspond to
the data on the rating plate.
The temperature of the process must be taken into account when selecting
the sampling point.
Heating of the probe or preliminary filter above the temperature limit given in
table 5 must be prevented.
It must be ensured that the temperature class of the probe
corresponds to the ignition temperatures of the combustible
gases/vapours.
Select the optimum sampling point in accordance with general guidelines or
agree on a sampling point with the responsible authorities.
Place the sampling point in such a way that there is sufficient space for
installation and removal of the probe. Do not forget to include the insertion
length of the sample tube in your considerations.
Easy access to the probe must be ensured to facilitate later maintenance
work.
The customer-side sample nozzle should be dimensioned so that the
temperature of the nozzle is always above the process dew point to prevent
corrosion and blockages.
If the ambient temperature in the area of the nozzle is higher than 60 °C
[140 °F] due to radiant heat, a radiant heat reflective plate must be installed
locally to protect the probe.
The mounting flange connection for the nozzle should be DN 65 PN 6. If
another connection size is desired, an optional intermediate flange adapter
/SO10 is available.
The necessary minimum flange size or minimum nozzle diameter depends
on the diameter of the sample tube or preliminary filter used.
