CERAGOLD Probe
- Installed directly in the furnace atmosphere
- Patented design delivers accuracy and repeatability
- mV signal can be used to calculate carbon potential, dew Point or oxygen
- Typical thermocouples - S, R, K or N
- State-of-art probe design optimises burn-out performance
- Engineered to be re-built and re-certified by us.
- Diffused ceramic (Cermet) coating gives protection to the RA330 alloy sheath against temperature and carbon erosion (aka green rot).
Driven by a desire to improve probe performance in exceptionally high temperature and carbon atmospheres, SSi developed the industry's first "third generation" oxygen probe - CERAGOLD PROBE. We are successfully applying cermet coating techniques to extend probe sheath life and to reduce the catalysis effect with methane that is present with other probe alloy sheaths currently used. This design feature, along with the unique anode contact configuration is the subject of a U.S. patent.
Heat treaters operating equipment at the elevated temperatures(>950°C) and carbon potential (>1.25%C) will experience the most significant gain in probe life. The cermet sheath treatment creates a deep, impenetrable layer to protect all exposed surfaces from the carburising atmosphere. Reducing the amount of nickel exposed at the surface reduces soot formation and virtually eliminates high temperature corrosion (green rot).
CERAGOLD coated sheath versus non-coated sheath.
CERAGOLD's optimised burn off capability is an additional feature which helps eliminate probe accuracy and response problems. CERAGOLD is designed with a 1/2" pipe sheath, not 3/4" like some other probes. This requires much lower volumes of burn off air to reach the probe electrode tip and greatly contributes to rapid, efficent burn off and hence to longer term accuracy and process consistency.
