Rosemount Hi-Temp 5081

Two-Wire In Situ Oxygen Analyzer (550° to 1400°C). MEASURES CLOSER TO THE FLAME WHILE MAINTAINING INTRINSIC SAFET.

Traditional in situ oxygen flue gas analyzers utilize zirconium oxide sensors to measure excess oxygen in process flue gas. These zirconium oxide sensors use a principle of operation based on the Nernst equation. This principle requires that the sensor cell be maintained at a high operating temperature using a heater that is powered via the analyzer’s electronics div>
 

Many operators of combustion processes have applications that involve hazardous gases in the process itself or in the ambient gases in the area where the analyzer’s electronics are installed. These operators are often concerned that the cell heater can serve as an ignition source to these hazardous gases inside the process or that the electronics can provide ignition to hazardous process or ambient gases that may be present. As a result of these concerns, these users must purchase oxygen analyzers with costly protection features.
