1.7 Technical Data
High sample and calibration gas pressures
High gas pressure
Above 1100 hPa to max. 1500 hPa (take
care
of the measurement principles limits!)
Maximum fl ow 1,5 l/min.
Special conditions:
The gas paths need additionally to be pro-
tected by suitable inline fl ame arrestors, designed
and approved for the applied higher gas
pressure. These inline fl ame arrestors need to be
installed outside the analyzer and in addition
to the fl ame arrestors provided by the analy
zer. A separate analyzer fl ame arrestor has
to
be installed, operating as a breathing device.
Connection of breathing device:
The external output of the breathing device
(exhaust) can be open to the ambience of the
analyzer, if the measured gas concentration is
below 25 % V-V LEL. Otherwise it must end
in a safe area.
Purging the housing with clean gas when e.g. measuring low concentrations
Maximum gas fl ow 2 l/min.
Permitted purge medium: Inert gas or air. Dry, clean, free of corrosives
or components containing solvents, and free
of components to be measured.
Its temperature must correspond to the am-
bient temperature of the analyzer, but be at
least within the range 20–35 °C (68–95 °F).
Special conditions:
The medium must be supplied via a separate
fl ame arrestor. Another fl ame arrestor must
be installed, operating as a breathing device.
Connection of breathing device: The external output of the breathing device
(exhaust) can be open to the ambience of the
analyzer if inert gas is used as purge medium.
If air is used, the output must end in a safe
area, if the measured gas concentration is above
25 % V-V LEL.
Take care of special conditions for safe use (
S-6 or 1-5 ) !
