Oxyfire High-Temperature Series
This in-situ oxygen sensor measures oxygen concentrations directly in the "high heat" zones of high
temperature furnaces, boilers and incinerators. They are intrinsically safe, requiring no electrical input
power, and generating only a low millivolt output. For product literature

Reader).
Available in a number of standard lengths up to 48"
(1200 mm) Field performance can be easily verified using integral
calibration gas port "B", "S", and "R" thermocouples are available Alumina, Silicon Carbide, HR160 Alloy and Zirconia protection sheaths are available CE Marked and TUV Certified Intrinsically Safe per EN50 014 (1977) clause 1.3 Temperature Range: 1200 °F to 3000 °F (649-1648°C) Robust design eliminates "auxiliary sheaths"
required on lower quality products 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 - one more failure point in low-end designs Patented "boot" provides fast response while
protecting the outer electrode and preventing the 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 air-tight enclosure
for electrical connections Classified configurations available 12-month warranty
This twenty-year-old design is often imitated but never equaled for economical oxygen sensing. Marathon's OX probe is the original "side-hole" high-temperature oxygen probe and the industry's best, most proven, low-cost solution for customers that want reasonable accuracy at the lowest possible price. The key components of the OX are replaceable and while it is not recommended for demanding applications such as steel reheat furnaces, glass furnaces, boilers and incinerators, it is well suited to less demanding applications such as annealing and threshold alarming. Owing to its side-hole design it exhibits lower accuracy and measurable drift when compared Marathon's Oxyfire. The side-hole design also makes it susceptible to slag, making an auxiliary sheath necessary in dirty environments.

This in-situ oxygen sensor is the most valued engineered sensor in its class, with response times of less than
3 seconds. Unlike competing sensors, the LOROX can be maintained and repaired while in place, saving wasteful
downtime while minimizing risk of damage. This sensor has been designed to directly replace other popular
zirconia sensors without modifications to wiring or physical mounting arrangements.
The
Sentinel-ESTM from Marathon Sensors is a
breakthrough, cost-effective solution for monitoring oxygen concentration in
applications running at temperatures or with environments too hostile or
impractical to use in-situ probes. With a replacement (not rebuild) cost less
than one-third that of conventional probes, the Sentinel-ESTM
is an ideal solution for trouble-free and cost-effective extractive oxygen
sensing..
