The Latest Breakthrough For Combustion Flue Gas Analysis The Oxymitter In Situ Oxygen Transmitter was the world’s first in situ, zirconium oxide-based oxygen transmitter for flue gas measurement. These oxygen measurements can be used in a control system or by a boiler operator to fine tune burner fuel/ air ratios for maximum efficiency. Ideal for: n Boilers n Process Heaters n Kilns n Reheat furnaces Emerson Process Management is the leader in oxygen flue gas analyzer technology. Our in situ, zirconium oxide oxygen analyzers have long been established as industry standards. We’ve combined...

Advanced Software Features (available only with the Xi electronics) Extended Process Temperature Range to 800°C (1562°F) The oxygen analyzer employs a heater and thermocouple to maintain a temperature setpoint at 736°C (1357°F). Temperature control is maintained within ±1°C to process temperatures of about 705°C (1300°F). This is satisfactory for most applications, but excursions to higher temperatures can occur in many processes. In these instances, the heater is turned off and the process temperature is utilized to heat the sensing cell. The oxygen reading is adjusted immediately to...

Programmable Reference The zirconium oxide sensing technology has historically measured process oxygen by using ambient or instrument air as a reference (20.95% oxygen). The sensor develops most of its signal at the low oxygen levels typically found in combustion flue gases (2-4% oxygen) and is most accurate at these levels. When measuring at levels near ambient, however, the sensor develops only a few millivolts of signal and accuracy degrades. The zirconium oxide sensing technology has historically measured process oxygen by using ambient or instrument air as a reference (20.95% oxygen)....
