22 EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A
Sample gas inlet conditions with positive pressure in the sample
gas feed path
Sample gas composition
A special version of the gas analyzer is suitable for measuring
non-flammable and flammable gases under positive pressure. Under no
circumstances may the sample gas be potentially explosive.
If the sample gas consists of non-flammable gases and vapors, the oxygen
content may be max. 21 % vol. as per atmospheric conditions.
If the sample gas consists solely of oxygen and flammable gases and vapors,
it is generally not potentially explosive if the oxygen content is safely limited
to max. 2 % vol.
Flammable gases which are potentially explosive under the conditions ap-
plicable for the analysis, even without the presence of oxygen, may only be
contained in the mixture to be analyzed in non-safety-critical concentra-
tions.
The gas analyzer may not be used for measuring gases that attack the mate-
rials in contact with the sample medium (e.g. gases containing chlorine).
