5081FG High Temperature Oxygen Analyzer

Brand: Rosemount
Request Information
The Rosemount 5081FG In Situ High Temperature Oxygen Transmitter provides a continuous, accurate measurement of the oxygen remaining in flue gases from combustion processes ranging from 550° to 1,400° C. 

The 5081FG is an explosion-proof and intrinsically safe loop-powered device which utilizes a zirconia sensor that is heated solely by process heat.
Features
  • The in situ probe and electronics are intrinsically safe
  • Operates in process gases ranging from 550° to 1,400° C (1,022° to 2,550° F)
  • 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
