The GOLDPROBE is a zirconia oxygen sensor used for atmosphere measurements which include non-oxidizing, reducing, neutral and carburizing processes.

Designed for HIGH temperature and HIGH carbon applications.

CeraGold Probes include a cermet coating to extend probe sheath life and to reduce the catalysis effect with methane that is present with other probe alloy sheaths. This design feature, along with the unique anode contact configuration, is the subject of a recently awarded U.S. patent.

Heat treaters operating equipment at elevated temperatures ( > 1750°F ) and carbon potential ( > 1.25% C ) will experience the most significant gain in probe life. The cermet sheath treatment creates a tenacious, impenetrable layer to protect all exposed surfaces of the probe sheath from the carburizing atmosphere. This reduces the amount of nickel exposed at the surface, reduces soot formation, and virtually eliminates high temperature corrosion (green rot).

CERAGOLD’s “on the fly” burn off capability eliminates nagging probe accuracy and response problems. CeraGold is designed with a 1/2″ pipe sheath, not 3/4″ as with other probes. The 1/2″ size requires much lower volumes of burnoff air to reach the probe electrode tip. This feature greatly contributes to rapid, efficient probe burnoff, and hence to longer term probe accuracy and process consistency.

Patented design delivers accuracy and repeatability for Carbon potential, dew point, and oxygen. State-of-the-art probe design features high velocity burn-out. Engineered to be rebuilt at 50% of the original cost.

Designed with the traditional Gold Probe features, Nitro Probes deliver precision and repeatability in controlled atmospheres with a focus on lower temperatures which would be typically found in ferritic nitrocarburizing applications. Nitro Probes are ideal for measurement of carbon potential above temperatures of 1100 F (593.3 C) and pre- and post-oxidation processes at lower temperatures.

Super Systems, Inc. offers their most recent innovation with respect to measuring the atmosphere output from an endothermic generator. The BAZOOKA fits through the side of the generator, features its own integral sample well, and fits easily into a standard 1 1/4″ hole. Designed with the ability to burn off, the BAZOOKA should be the next probe to control your generator. Specifically designed to control endothermic generators. Used on rotary and muffle furnaces. Installed in combustion chamber. Integral sample well. Operates at 1500 – 1600°F (816 – 871°C) for optimum life.

Why an HP2000 self-heated oxygen sensor?


There are certain applications where an in situ oxygen probe is impractical. For those applications Super Systems, Inc. recommends the HP2000 self-heated oxygen probe. This system supplies the temperature required to make an oxygen probe function. For some applications, such as a multi-tube generator or a rotary retort furnace, this probe will allow you to extract a continuous sample of the atmosphere stream and pass it by a standard oxygen probe. Applications:

• Rotary Furnaces Sample line extended into furnace beyond quench chute
• Opposite-end from atmosphere introduction
• Adequate filter system
• Conservative addition of enriching gas
• Modular endothermic generator
• Manifold “sample” lines
• Allow for condensation drip
• Fixed sample lines
• Use natural gas as “oxygen getter”
• Low temperature applications
• Nitrogen-based low temperature, miscellaneous protective atmospheres
• %Oxygen in residual combustion gases.
• Manual “shut-off” valves are suggested
• Sintering/Muffle furnaces
• No need for high temperature probes

Probe redundancy for load assurance and an alternate in-situ reading of the furnace atmosphere.  Function: The Model 9120 RPS reads the signal from two oxygen probes located in the same furnace, automatically switching the output from the Model 9120 RPS to the probe with the highest millivolt output.
