CONTINUOUS GAS ANALYZERS | CI/EL3000-EN REV. C
… 4 Installation
Fidas24 – Connecting the sample gas line to the heated sample gas connection
NOTE
Damage to the gas analyzer
Damage to the gas analyzer, due to melting of the factory-
mounted plastic plugs in the sample gas inlets.
• Remove the plastic plugs from the sample gas inlets
before commissioning.
Material of the sample gas line
Use a PTFE or stainless steel sample gas line! (Recommended:
use heated sample gas line TBL 01) The medium temperature
can be up to 200 °C!
Sample gas line connection
The heated sample gas line must be connected directly to the
sample gas inlet. Make sure that the O-rings are seated correctly
and that the sample gas pipe has been inserted into the sample
gas connection until it stops.
Unused sample gas inlets
• When the analyzer draws in the sample gas through the
sample gas line, the unused sample gas inlets must be sealed
using the screw plugs (installed at the factory).
• When the sample gas is under gauge pressure, a sample gas
inlet must be open and connected to an exhaust gas line so
that there is no gauge pressure in the analyzer.
Screwed connections and O-rings
The required screwed connections and o-rings are included in
the supplied accessories bag.
Maximum length of the sample gas line
The maximum length of a heated sample gas line (inner diameter
4 mm) is 60 m.
Provide for Sample Gas Line Purging
Install a shut-off valve in the sample gas line (highly
recommended for pressurized sample gas) and provide the
option of introducing an inert gas, e.g. nitrogen, from the gas
sampling point, for purging of the sample gas line.
