• The gas analyzer may not be used for the measurement of
ignitable gas / air or gas / oxygen mixtures
Magnos206 – sample gas input conditions
Temperature
• The sample gas dew point should be at least 5 °C below the temperature
throughout the sample gas path. Otherwise a sample gas cooler or
condensate trap is required.
• When there is a direct connection to the sample chamber, the maximum
sample gas dew point is 55 °C.
• Water vapor content variations cause volume errors.
Designation of gas connections
The analyzer is operated under atmospheric pressure; the sample gas outlet is
open to atmosphere.
Internal pressure drop:
Permissible absolute pressure range: 800 to 1250 hPa.
Operation under higher pressure:
Absolute pressure ≤ 1250 hPa:
Absolute pressure ≥ 1250 hPa:
The analyzer module is function-tested for 5000 hPa internal pressure without
damage.
Flow rate
< 5 hPa at standard flow rate of 60 l/h.
Operation under lower absolute pressure
(e.g. at altitudes above 2000 m) on
request.
A pressure sensor is required to
compensate for pressure influences.
An optional internal pressure sensor can
be connected to the sample gas path.
An external pressure sensor must be
connected to the sample gas path. The
pressure compensation must be
calculated externally.
30 to 90 l/h
Abrupt changes in the sample gas flow
rate should be avoided when using highly
suppressed measurement ranges.
Corrosive gases
If the sample gas contains Cl
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 is suited for measuring flammable gases in a non-
explosive environment.
Observe the special conditions when measuring flammable
gases, see Special conditions for the measurement of
combustion gases on page 41.
Pressure sensor
The pressure sensor is optionally installed in the gas analyzer,
see Pressure sensor on page 36.
The pressure sensor is connected to a connection socket via an
FPM tube.
For measurements in suppressed measurement ranges, the
sensor and sample gas outlet have to be connected to each
other via a T-piece and with the use of short conductors.
Make especially sure that the gas discharge line is as short as
possible or has a sufficiently large inside diameter (min. 10 mm)
in case of a larger length.
