Installation site
Ambient temperature
During operation with analyzer module installed in a system housing
+5 to +50 °C without electronics module
+5 to +45 °C with electronics module or with power supply only
Vibrations/shocks
max. ±0.04 mm at 5 to 20 Hz
Sample gas
Sample gas inlet conditions
Temperature The dew point of the sample gas must be at least 5 °C
lower than the lowest ambient temperature in the overall
sample gas path. Otherwise, a sample gas cooler or con-
densate trap is required.
When there is a direct sample chamber connection the
maximum sample gas dew point is 55 °C.
Fluctuations in water vapor content cause volume errors.
Pressure Operation under atmospheric pressure: The sample gas
outlet is open to atmosphere. Internal pressure drop
< 5 hPa with standard flow rate 60 l/h. Permissible abso-
lute pressure range: 800 to 1250 hPa. Operation under
lower absolute pressure (e.g. at altitudes above 2000 m)
on request.
Operation under elevated pressure: A pressure sensor is
required for pressure influence compensation. Absolute
pressure ≤ 1250 hPa: An optional internal pressure sensor
can be connected to the sample gas path. Absolute pres-
sure ≥ 1250 hPa: An external pressure sensor must be
connected to the sample gas path.
The analyzer module is function-tested for 5000 hPa in-
ternal pressure without damage.
Flow 30 to 90 l/h
Abrupt changes in the sample gas flow rate should be
avoided when using highly suppressed measurement
ranges.
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)).
Corrosive gases
If the sample gas contains Cl
2
, HCl, HF or other corrosive components, the
analyzer may only be used if the sample gas composition has been taken
into account by the manufacturer for the configuration of the analyzer.
Flammable gases
The analyzer module is suitable for the measurement of flammable gases
and vapors under atmospheric conditions (p
abs
≤ 1.1 bar, oxygen content
≤ 21 vol.%). Temperature class: T4.
