Installation
4.3 Installation - Gas Conditioning
In order to ensure trouble-free operation, spe
-
cial attention must be paid to the preparation
of the gases:
All gases must be conditioned
before supplying to the analyzer,
to ensure they are
•
dry,
•
free of dust and
•
free of any aggressive com-
ponents which may damage
the gas lines (e.g. by corrosi-
on or solvents) .
Flammable gases must not be
supplied without suitable pro-
tective measures.
If moisture cannot be avoided, it is necessary
to ensure that the dew point of the gases is at
least 10 °C (18 °F) below the ambient tempe
-
rature to avoid condensate in the gas lines.
The X-STREAM field housings can optionally
be fitted with heated piping to enable the use
of gases with a maximum dew point of 25 °C
(77 °F) - consult factory.
Pressure and gas flow must remain within
the values given in the „Measurement
Specifications“ section within this manual.
Hints for selected gases
•
Calibration gases for CO and NO need
to be moistured by supplying them via a
cooler.
