Thermocouple selection issue
Thread Content
For the sulfur production furnace we have, we chose S-type thermocouples; however, they got damaged after just a few months of use. The operating temperature is around 1200–1300 degrees. Could any expert suggest what type of thermocouple would be suitable? What other manufacturers are there?
Also, the porcelain protective sleeves that were used last time were all burned out; they’re not durable at all
It mainly comes down to the issue of protective sleeves; choose those that are wear-resistant. There are many manufacturers producing such sleeves nowadays, so it’s best to opt for products from reputable manufacturers with a good reputation. The quality of products can vary greatly depending on the manufacturer, so it’s advisable to try products from several different manufacturers.
The damage to your thermocouple is mostly caused by damage to the protective sleeve

The problem with this estimation lies in the sleeve
You can try using ours; we use it very well in power plants
Our experience is: don’t worry about which manufacturer or what type of sleeve to use. As long as the junction box is sealed, it can be used for a long time. It doesn’t matter whether the sleeve breaks or not; what kind of sleeve it is is unimportant. Of course, it’s best if nothing breaks, but that’s not the key!
