Sensor
Principle of
Operation
Direct sensing insitu probe suitable for applications where the flue gas
temperature does not exceed 1250°F (677°C) and where combustibles
measurement is not required. Zirconium oxide for net oxygen mea-
surement.
Output Range
From 0-1% to 0-100%
Accuracy ± 1% of measured value or ± 0.05% oxygen, whichever is greater
Response 63% of a process step change < 20 secs.
Drift
