High Temperature Oxygen Analyzer Model 5081FG
The Model 5081FG Two-Wire In Situ Oxygen Analyzer utilizes a zirconium oxide sensor to measure excess oxygen in combustion processes and can operate at high temperatures 550º to 1400ºC (1022º to 2550ºF).
|
- The in situ probe and electronics are intrinsically safe
- Operates in process gases ranging from 550ºC to 1400ºC (1022ºF to 2550ºF)
- Provides HART® / AMS communications
- Provides accuracy of +/- 1.5% of reading
- Provides protection from hazardous process or ambient gases, preventing explosions without requiring field-mounted electrical barriers, flame arrestors or special enclosures. Explosion-proof conduit is not required for cabling.
- Provides accurate oxygen flue gas analysis closer to the flame in boiler applications; enables accurate flue gas analysis in high temperature process heater or furnace applications
- Provides convenient and cost-effective operator access to key analyzer parameters; provides analyzer diagnostic capabilities from the terminations room, instrument maintenance shop or control room.
- Best accuracy specification for analyzer of its type in the industry; enables tighter energy control in process which helps user reduce energy costs; improves process throughput.
- Net O2 range: 0-25%
- System accuracy: +/-1.5% of reading or 0.05% O2, whichever is greater
- System speed response in flue gas: intial response- less than 3 seconds T90 response- less than 10 seconds
- Probe Lengths: 508 mm (20 in.), 660 mm (26 in.), 965 mm (38 in.)
