Oxygen Sensors
Combustion oxygen sensors for optimizing burner efficiency and emissions.
UPC-Marathon Oxygen Sensors for combustion optimization provide continuous monitoring of excess oxygen in flue gases from industrial burners and furnace heating systems. Accurate oxygen measurement enables optimal air-fuel ratio adjustment for maximum thermal efficiency, reduced fuel consumption, and lower emissions in heat treatment furnace heating systems.
Available in several standard lengths up to 48″ (1,200 mm)
Field performance can be easily verified using integral verification gas port
“B,” “S,” and “R” thermocouples are available
Alumina, silicon carbide, HR160 alloy and zirconia protection sheaths are
available
CE marked
Intrinsically Safe under EN50 014 (1977) clause 1.3
Temperature range: 1,000 °F – 3,000 °F (max) / 538 °C – 1,649 °C (max)
Robust design eliminates “auxiliary sheaths” required on lower quality products
Single side connections ensure cables are safely away from the hot furnace wall
Compatible with standard conduit fittings
Proven track record: used in more furnaces, boilers and incinerators than all
other high-temp probes combined
Longest life available
No drift or accuracy problems common to “side hole” probes
High quality construction eliminates the need for cooling air (another failure
point in low-end designs)
Patented “boot” provides fast response while protecting the outer electrode and
preventing accuracy problems that plague foil-based electrodes
Proprietary, application-specific installation configurations maximize life and
accuracy in high-slag environments
Machined 6061T6 aluminum head provides airtight enclosure for electrical
connections
Classified configurations available
12-month warranty
