Principle of Operation:
Convective oxygen analyzer using a zirconium
oxide electrochemical cell for oxygen measurement.
Completely field serviceable.

Display Range:
Oxygen: 0.1-100%

Output Range:
Oxygen: From 0-1% to 0-100%

Accuracy:
±0.75% of measured value or ±0.05% oxygen, whichever is greater

Response:
< 3 sec. to calibration gas. 63% of process step change <16 secs. with 24″ probe

Drift:
< 0.1% of cell output per month (< 0.005% O2 per month with 2% O2 applied)

Flue Gas Temperatures/Probes:

  • to 1300°F (704°C) with 316 SS
  • to 1875°F (1024°C) with RA330
  • to 2800°F (1537°C) with mullite

Probe Lengths:
24″, 36″ and 48″ (0.60m, 0.91m and 1.21m)

Max. Sample Dewpoint:
450°F (232°C) standard. High dewpoint sensors are available for sample dewpoints up to 700°F (371°C).

Sample Pressure:
±2 psig: no adjustments required
±2 to ±9 psig: software selectable
±10 psig and above: consult factory

Environment:
Ambient Temp.:
-5°F to 160°F (-20°C to 71°C),
-5°F to 140°F (-20°C to 60°C) w/Div. 2 Option
Bulletin P-210
Relative Humidity:
10% to 90%, non-condensing

Enclosure:
General purpose, weather resistant, stainless steel. Explosion-proof and purged versions are optional.

Power Requirements:
115 VAC, ±10%, 47-63 Hz., 600 VA max. (650 VA max. w/floor mount option);
230 VAC, ±10%, 47-63 Hz., 1850 VA max. (1900 VA max. w/floor mount option)

Calibration Gas Requirements:
Use calibration gases @ 10 psig, 1.5 scfh (0.70 kg/cm2, 0.7 L/min.)
O2 Span Gas:
Air or from 1.0% to 100% O2, balance N2
O2 Zero Gas:
2% or from 0.1% to 10% O2, balance N2

Excess Fuel Software Option:
Extends operating range of analyzer from excess oxygen only to include substoichiometric conditions (excess fuel). Allows two-point calibration in excess fuel range. Measure, display, and provide alarms and analog outputs as follows:

Display Options:
Excess fuel, combustibles, oxides/fuel, fuel/oxides, combined excess oxygen/excess fuel (combustibles).
Display Range: 0-50% excess fuel
Output Range: 0-1% to 0-50% excess fuel
Alarms: Standard alarms can be used for high or low excess fuel levels.
