356 AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B
Oxygen sensor: Operating specifications
Linearity deviation Linear in the range of > 1 vol.% of O
2
Repeatability ≤ 0.5 % of span
Zero drift Stable in the long-term due to absolute zero point
Sensitivity drift ≤ 1 % of the measured value per week
Output fluctuation (2
σ)
≤ 0.2 % of span at electronic T90 time (static/dynamic)= 5/0 s
Detection limit (4
σ)
≤ 0.4 % of span at electronic T90 time (static/dynamic)= 5/0 s
Flow influence Flow rate in 20 to 100 l/h: ≤ 2 % of the span
Temperature influence Ambient temperature in permissible range: ≤ 0.2 vol.% of O
2
per 10 °C
Air pressure effect At zero point: no influence effect;
On sensitivity without pressure correction: ≤ 1 % of the measured value per
1 % air pressure change;
On sensitivity with pressure correction: ≤ 0.2 % of the measured value per
1 % air pressure change.
Pressure correction is only possible if the oxygen sensor is connected to an
analyzer module with an integral pressure sensor. Pressure sensor working
