48 AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B
Fidas24: Preparation for installation
Installation site
Ambient temperature
During operation with analyzer module installed in a system housing
+5 to +45 °C without electronics module
+5 to +45 °C with electronics module or with power supply only
Vibrations/shocks
max. 0.5 g, max. 150 Hz
Sample gas
Sample components
Hydrocarbons. The concentration of the gas components in the sample gas
path must not exceed the temperature-dependent LEL. The analyzer tem-
perature is 180 °C.
Sample gas inlet conditions
Temperature ≤ Thermostat temperature (thermostat temperature for
sample gas path, detector and air jet injector ≤ 200 °C,
pre-set ex works to 180 °C)
Inlet pressure p
abs
= 800 to 1100 hPa
Flow Approx. 80 to 100 l/h at atmospheric pressure (1000 hPa)
Humidity ≤ 40 % H
2
O
Remark: Sample gas temperature, pressure and flow rate should be main-
tained constant to such a degree that the fluctuation influence on the accu-
racy of measurement is acceptable (see also chapter "Analyzer module oper-
ating data" (see page 346)).
Sample gas outlet conditions
The outlet pressure must be the same as the atmospheric pressure.
Flammable gases
The gas analyzer may be used for the measurement of flammable gases
provided that the flammable portion does not exceed 15 vol.% CH
4
or
C1 equivalents.
Further sample gas inlet conditions
The sample gas may not be explosive at any time.
The analyzer module must not be used for measurement of gases containing
organometallic compounds, e.g. leaded gasoline additives or silicone oils.
