Opis
The SSi CeraGold probe shares the design of the SSi Gold Probe with one key difference: a diffused ceramic coating that gives the oxygen probe resistance to high temperatures and aggressive atmospheres. The patented coating forms an impenetrable layer that protects the RA330 alloy sheath against temperature and carbon erosion, also known as green rot.
The coating also reduces the catalytic effect between nickel and methane that occurs in many oxygen probes, which limits sooting and keeps the measurement stable in carbon-rich atmospheres. Furnace users operating above 950 °C with a carbon potential above 1.25 %CP see the most significant gain in probe life.
As with the Gold Probe, every oxygen sensor eventually degrades, but the CeraGold is engineered to be rebuilt at low cost and at short notice.
