Requirements of the Gas Supply
The analyzer system uses the connected instrument air continuously for the supply of
reference air, and during calibration and system test respectively, for the supply of test air (test gas 1).
Instrument air supply
for reference air
/
test air
Specification:
According to ISO 8573-1 class 2
(Particle size max. 1
m,
Particle density max. 1mg/m³,
Oil content max. 0,1mg/m³,
Pressure dew point max. -40 °C or 10 °C below lowest possible ambient temperature
Constant 20,95 Vol. %O
2
Input pressure:
2-10 bar
Flow rate
continuously maximum 40 l/h (for reference air supply)
180 l/h during calibration
Test gas (test gas bottle)
for calibration / system test
Input pressure:
max. 3 bar
Specification
test gas 1 (optional):
21% O
2
in N
2
(synthetic air – in case instrument air is not available)
Specification
test gas 2:
The test gas used for calibration purposes must have the exact same composition as the
test gas specified in the test certificate. The test certificate can be found attached to the
probe / sensor on delivery.
The test gas recommendations for O
2
and CO
e
sensor may possibly differ. In this case,
the sensors must be individually calibrated.
Flow rate
180 l/h at 1,1 bar (+/- 0,1).
Note
The flow rate of the test gas bottle is set via the bottle pressure regulator.
