GAA610-M
ADVANCED EMISSION GAS MONITORING SYSTEM | OI/GAA610-M-EN REV. B 13
Heated sample gas line
The heated sample gas line is directly connected to the filter at
the probe. The core is a PTFE hose. The line is heated to 180 °C
(356 °F).
The temperature is controlled with a Pt100 resistance
thermometer and the power/temperature is adjusted with a
temperature controller installed in the cabinet. In case of a
deviation from the set value a message is generated and
displayed on the AO2020-Display.
Temperature controller
A Temperature controller is used to control the temperature of
the heated sample gas line.
An alarm signal is output as soon as the temperature drops
below the minimum temperature limit.
Solenoid valve
A solenoid valve is installed to switch between measuring gas
and ambient air during calibration and standby mode.
Aqua stop filter
The aqua stop filter is the final protection for the analyzer. The
aqua stop filter holds back any humidity.
AO2020-Uras26 gas analyzer
The AO2020-Uras26 gas analyzer is integrated into the analyzer
system for measuring CO
2
and SO
2
.
The main components are an infrared source (lamp), a sample
cell, a wavelength filter, and the infrared detector.
The sample gas is pumped into the sample cell, and the gas
concentration is measured electro-optically by its absorption of
a specific wavelength in the infrared wavelength range.

Figure 3: Sample Gas Cooler SCC-C
The sample gas cooler defines the water content of the sample
at a certain dew point (typically 3 °C). Therefore, the temperature
of the sample falls from approx. 180 °C to the set point of the
sample gas cooler and condensation will occur. The condensate
is removed with a hose pump and collected in a separate bottle.
The sample gas cooler is controlled by the system and the
following signals can be output:
• Condensate level:
The level of the condensate collecting bottle is monitored
and a signal will output (displayed via a red lamp on the
front panel) when maintenance / emptying the bottle is
required.
• Fault cooler:
A status signal "fault cooler" is set if the cooler
temperature is too high. The signal is also provided as
"Failure" status signal.
• Failure alarm:
If a failure of the cooler is detected, the feed pump is
switched off and the system is set to system failure
mode. The system failure mode is displayed on the panel
and provided as a status signal.
