AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B 101
Fidas24: Connecting the sample gas line (heated sample gas
connection)
CAUTION
If a plastic vent plug has been inserted in the sample gas inlet in the fac-
tory, it must be removed without fail before commissioning the analyzer
module!
Material of the sample gas line
Use a sample gas line of PTFE or stainless steel! (Recommendation: use a
heated sample gas line TBL 01.) The temperature of the medium can be up
to 200 °C!
Connecting the sample gas line
The heated sample gas line is connected directly to the sample gas inlet. In
this respect, the correct seat of the O-rings must be ensured and also that
the sample gas tube is inserted all the way in into the sample gas connec-
tion.
Unused sample gas inlets
If the analyzer module draws in the sample gas through the sample gas line,
the unused sample gas inlets must be sealed with the screw plugs (screwed
in in the factory).
If the sample gas is under positive pressure, a sample gas inlet must be
open and connected to an exhaust gas discharge line, so that no positive
pressure builds up in the analyzer module.
Fittings and O-rings
The requisite fittings and O-rings are included in the supplied accessories
pack.
