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

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
