PROCESS INSTRUMENTS
flue gas oxygen, combustibles & methane analyzer
Close-coupled extractive design for fast response in a wide range of flue gas
applications up to 3000°F (1648°C). Completely field serviceable.
SENSOR
Principle of Operation: Zirconium oxide
for net oxygen measurement and dual
hot-wire catalytic detectors for both combustibles and methane.
Output Range:
Oxygen: From 0-1 to 0-100%
Combustibles: From 0-2,000 PPM to
0-10,000 PPM
Methane: 0-5%
Accuracy:
Oxygen: ±0.75% of measured value or
±0.05%, whichever is greater
Combustibles: ±2% of full scale output
range
Methane: ±5% of full scale output range
Response - Oxygen: 90% of a step change < 13 seconds
Drift: < 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)
Max. Flue Gas Temp. / Probe Type / Lengths:
1300°F (704°C) / 316 SS / 36” - 108”(91 cm - 274 cm)
1875°F (1024°C) / 310 SS / 36” - 108”(91 cm - 274 cm)
3000°F (1648°C) / Hexoloy® / 24” - 72” (60 cm - 182 cm)
Max. Sample Dewpoint: 392°F (200°C)
Sample Pressure: ±10 in. water gauge
Environment:
Ambient Temp.:t -5°F to 160°F (-20°C to 71°C); -5°F to
140°F (-20°C to 60°C) with Div. 2 Option
Relative Humidity: 10% to 90%, non-condensing
Enclosure: Lift-off NEMA 3R, weather resistant, stainless
steel. Optional hinged NEMA 4X (IP65), explosion-proof,
purged, and floor mount versions available.
Power Requirements: 115 VAC, ±10%, 47-63 Hz, 700 VA
max. (750 VA max. w/floor mount option); 230 VAC, ±10%,
47-63 Hz, 1950 VA max. (2000 VA max. w/floor mount option)
Calibration Gas Requirements: For sensors without flame
arresters use calibration gases @ 10 PSIG, 1.5 SCFH (0.7
L/min.)
For sensors with flame arresters use calibration gases @ 10
PSIG, 2 SCFH (1 L/min.)
Note: Flame arresters are standard in all certified Div. 2 and
ATEX analyzers
O2 Span Gas: Air or from 1.0% to 100% O2, balance N2
O2, Comb. & CH4 Zero Gases: From 0.1 to 10% O2,
balance N2
Comb. Span Gas: 60 to 80% (PPM ranges) or 40% to 60%
(% ranges) of the selected comb. recorder output range in
certified equal mixtures of CO + H2, 3-4% O2, balance N2
SERIES 2000 CONTROL UNIT
CH4 Span Gas: 2% CH4, 8% to 10% O2, balance N2
Display: Four line x 20-character vacuum
fluorescent. Displays combinations of
oxygen, PPM combustibles, methane,
time and date, cell temperature, user programmable text, thermocouple mV or cell
mV. Password protection, programmable
pressure compensation and contextsensitive help are also provided.
Calibration: Oxygen cell lifetime extender. Calibrate or
verify calibration. Store last calibration and verification data.
Selectable calibration gas run time and process recovery
time. Timed automatic calibration with optional Remote
Calibration Unit.
Analog Output: Two isolated linear current outputs for O2 and one each for combustibles and methane. Select
O2, combustibles, methane, cell temperature, thermocouple mV or cell
mV. Each output can be 4-20 mA, 0-20 mA, 20-4 mA or 20-0 mA and
is fully scalable. Hold or track during calibration and select degree of
damping. Max. load 1200 ohms.
Alarms: Two independent oxygen alarms, each high or low selectable.
One alarm can be assigned as oxygen, calibrate or verify. Two high
combustibles and two high methane alarms. Set relays to energize or
deenergize on alarm.
Contact Rating: 0.5A, 30V, 10VA max. noninductive load, AC or DC
Diagnostics: Watchdog timer and service alarms. System test for A/D,
RAM, EEPROM and keypad. Display line 4 reserved for full text error
and diagnostic messages. Twenty entry event log.
Communications: RS-485 2-way addressable
Environment:
Ambient Temp.: 14° to 122°F (-10° to 50°C)
Relative Humidity: 10% to 80%, non-condensing
Power Requirements: Nominal 115-230 VAC ±10%,
47-63 Hz, 75 VA max.
