Sample gas inlet conditions under atmospheric conditions
Sample gas composition
The standard version of the gas analyzer is suitable for measuring
non-flammable and flammable gases under atmospheric conditions, which
can occasionally form a potentially explosive atmosphere.
The oxygen content of the sample gas mixture may be max. 21 % vol. as per
atmospheric conditions.
If the sample gas only consists of a mixture of oxygen and flammable gases
and vapors, it may be not potentially explosive under any circumstances.
This can normally be achieved 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).
Sample gas inlet and outlet conditions
Temperature
The sample gas dew point must be at least 5 °C lower than the lowest am-
bient temperature in the overall sample gas feed path. Otherwise, a sample
gas cooler or condensate trap is required. Fluctuations in water vapor con-
tent cause volume errors.
Inlet pressure
Absolute pressure max. 1100 hPa and gauge pressure max. 100 hPa
Flow rate
Uras26 20 to 100 l/h
Magnos206 30 to 90 l/h
Magnos28 30 to 90 l/h
Caldos25 max. 100 l/h
Caldos27 max. 100 l/h
Pressure drop at the flame barriers
Approx. 40 hPa at a flow rate of 50 l/h
Outlet pressure
The outlet pressure must be the same as the atmospheric pressure.
