Measures closer to the flame while maintaining intrinsic safety Traditional in situ oxygen flue gas analyzers use 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 operators must purchase oxygen analyzers with costly protection features. In addition, traditional in situ oxygen analyzers use metallic alloys that are also limited to temperatures below 1300 °F (701 °C). 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 oxygen measurement. Improved analyzer accuracy often results in significant fuel savings or improved processes throughout. The Rosemount 5081FG High Temperature Oxygen Analyzer uses a zirconium oxide sensor to measure excess oxygen in combustion processes. The cost-effective design enables it to accurately measure excess oxygen in process temperatures ranging from 1022 to 2550 °F (550 to 1400 °C). In addition, the analyzer is designed so that both its oxygen probe and electronics are intrinsically safe without requiring costly design modifications, such as flame arrestors. The oxygen probe is constructed of ceramic materials capable of withstanding high process temperatures.
