The gas paths need additionally to be
protected by suitable external inline fl ame
arrestors, designed and approved for the
installation area and for the applied high-
er gas pressure (above 1100 hPa to max.
1500 hPa; see gas parameter specifi cation
1-10). These inline fl ame arrestors need
to be installed outside the analyzer and in
addition to the fl ame arrestors provided by
the analyzer.
Note!
The external inline fl ame arrestors are not
subject of the analyzer certifi cation and may
be provided by the customer, or optionally by
EMERSON PROCESS MANAGEMENT.
A separate analyzer fl ame arrestor has to be
installed, operating as a breathing device,
limiting the internal pressure rise in case of
gas path leakage.
Connection of breathing device:
The external output of the breathing device (ex-
haust) may be open to the ambience of the ana-
lyzer, if the measured gas concentration is below
25 % V/V LEL. Otherwise it must end in a
safe area.
