Fidas24 – Connecting the sample gas line to the unheated 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.
Sample gas line connection
The unheated sample gas connection has only one sample gas
inlet.
If the sample gas is under positive pressure, a T-piece must be
connected between the sample gas line and the sample gas inlet.
The free connection of the T-piece must be connected to an
exhaust gas discharge line, so that no positive pressure builds
up in the analyzer module.
Maximum length of the sample gas line
The maximum length of the unheated sample gas line (inside
diameter 4 mm) is 50 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.
