Sample Gas Inlet
Conditions
(Atmospheric
Conditions)
Type of Gas Non-combustible and combustible gases under
atmospheric conditions which can form an explosive
environment (Zone 1).
Temperature Caldos 15-Ex, Caldos 17-Ex, Magnos 106-Ex: +5 to +50 °C
Uras 14-Ex: +5 to +45 °C
Inlet Pressure p
e
≤ 100 hPa (= 0.1 bar) or p
abs
≤ 1,100 hPa (= 1.1 bar )
Flow Maximum of 100 l/h, but not greater than the non-
explosion protected version of the analyzer module.
The maximum oxygen content of the sample gas mixture should be 21 Vol.-%,
corresponding to atmospheric conditions.
If the sample gas consists only of oxygen as well as combustible gases and vapors,
it must not be explosive under any conditions. As a rule this can be achieved by
limiting oxygen content to a maximum of 2 Vol.-%.
Combustible gases that are explosive under the conditions encountered in analysis
even when oxygen is excluded should be present in the mixture only in concentra-
tions that are not critical to safety.
