In-Situ Oxygen Analyzer - Hi-Temp 2-Wire HART Smart (550-1600°C) (5081FG)

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. 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. In addition, traditional in situ oxygen analyzers use metallic alloys that are also limited to temperatures in the range of 701°C (1300°F). This process temperature limitation prohibits the analyzer from being inserted close to the actual combustion process. Many operators prefer to measure flue gas oxygen close to the furnace or radiant section for a more representative O2 measurement. Improved analyzer accuracy can often result in significant fuel savings or improved process throughput.
