Principle of Operation:
Close-coupled extractive oxygen analyzer using a zirconium oxide electrochemical cell for oxygen measurement. Completely field serviceable.
Oxygen: From 0-1% to 0-100%
± 0.75% of measured value or ± 0.05% oxygen, whichever is greater
Oxygen: 63% of a process step change < 3 secs.
Oxygen: < 0.1% of cell output per month (< 0.005% O2 per month with 2% O2 applied)
Aspirator Air Requirements:
10 to 20 scfh (4.72 to 9.4 L/min) at 15 to
100 psig (1.05 to 7.04 kg/cm2)
Flue Gas Temperatures/Probes:
- to 1300°F (704°C) with 316 SS
- to 1875°F (1024°C) with RA330
- to 2600°F (1426°C) with mullite
- to 3200°F (1760°C) with alumina
36″ (91cm) to 108″ (274 cm) 316SS or RA330
24″ (60cm) or 42″ (106 cm), mullite or alumina
Max. Sample Dewpoint:
450°F (232°C) standard. High dewpoint sensors are available for sample dewpoints up to 700°F (371°C).
± 2 psig: no adjustments required
± 2 to ± 9 psig: software selectable
± 10 psig and above: consult factory
-5°F to 160°F (-20°C to 71°C);
-5°F to 140°F (-20°C to 60°C) with Div. 2 Option
10% to 90%, non-condensing
General purpose, weather resistant, stainless steel. Explosion-proof and purged versions are optional.
115 VAC, ± 10%, 47-63 Hz., 600 VA max.
(650 VA max floor mount option;
230 VAC, ± 10%, 47-63 Hz., 1850 VA max.
(1900 VA max. 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:
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.
