Sample gas path ("containment system")
Sample gas Flammable and non-flammable gases and vapors under atmospheric condi-
tions (p
abs
≤ 1.1 bar, oxygen content ≤ 21 vol.%); Temperature Class T4, for
Limas11 IR: T6; not potentially explosive under normal conditions, if poten-
tially explosive in the event of a fault, then only seldom and briefly (in ac-
cordance with Zone 2); (only for Limas11 IR:) occasionally potentially explosive
under normal conditions (in accordance with Zone 1), Temperature Class T4.
Mixtures of flammable gases and vapors and oxygen that are not explosive
under normal conditions or in the event of a fault. As a rule, these can be
achieved if the oxygen content is reliably limited to max. 2 vol.% or the
flammable component is reliably limited to max. 50 % LEL.
Flammable gases and vapors that are explosive under the conditions en-
countered during analysis, even when oxygen is excluded, may be present in
the mixture to be analyzed only in concentrations that are considered
non-critical according to safety regulations.
Flow max. 40 l/h
Pressure At sample gas inlet: max. positive pressure p
e
≤ 3 hPa,
at sample gas outlet: atmospheric
Turning off the sample gas by user when shutting down the analyzer and in case of an alarm (pressur-
ized enclosure failure) additional special conditions for operation with
flammable sample gas (see page 27)
