This oxygen transmitter takes high-stability zirconia solid electrolyte as the core sensing component. Based on the Nernst principle, it generates corresponding millivolt potential according to the oxygen partial pressure difference between reference air and measured flue gas. The built-in precision heating unit maintains the sensor at a constant operating temperature to eliminate temperature interference on detection results, achieving continuous real-time measurement of flue oxygen content without complex gas sampling and pretreatment devices. It adapts to conventional boiler flue gas monitoring, incinerator tail gas detection and industrial furnace atmosphere control scenarios, effectively guiding air-fuel ratio adjustment to cut fuel consumption and lower pollutant discharge.

The probe structure adopts heat-resistant alloy protective sleeve with anti-corrosion coating, coping with flue dust, water vapor and weak acid corrosive substances in actual working conditions. The integrated electronic module features strong electromagnetic immunity to resist interference from surrounding high-power fans and frequency conversion equipment. Equipped with local digital display and configuration buttons, field operators can finish range setting, calibration parameter modification and fault checking on site. Isolated 4–20mA analog output and relay alarm contacts are configured to transmit oxygen data to DCS systems; high/low oxygen concentration alarms can be configured to prevent incomplete combustion or excessive air intake.

The whole machine supports long-term continuous operation within standard industrial ambient temperature and 95% non-condensing humidity. Each unit passes calibration with standard oxygen gas sources and powered aging tests before factory shipment to guarantee long-term measurement stability. Dust accumulation on the probe filter and aging of the zirconia chip will gradually cause measurement deviation, which leads to poor combustion efficiency and increased operating costs. Replacing with genuine XMO2-1H-31 transmitters or matching spare probes can rapidly recover system detection accuracy and reduce equipment maintenance downtime.

New transmitters are deployed for boiler flue gas monitoring renovation projects, while spare products serve routine maintenance replacement of online analysis instruments. Accurate oxygen measurement data optimizes boiler combustion efficiency, reduces energy loss and exhaust emission compliance risks, providing reliable analytical data support for long-cycle safe and economical operation of industrial thermal systems.
