Linear in the range > 1 Vol.-% O
≤ 0.5 % of span
Stable over long-term due to absolute zero point
≤ 1 % of measurement range scale per week
= 5 / 0 sec.
≤ 0.4 % of the measurement range at electronic T90 time (static / dynamic)
= 5 / 0 sec.
Flow rate in 20 to 100 l/h range: ≤ 2 % of measurement range scale
Ambient temperature in permissible range: ≤ 0.2 Vol.-% O
• On sensitivity without pressure correction:
pressure change
• On sensitivity with pressure correction:
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 range: p
≤ 30 seconds, depending on sample gas flow and system layout
