What type of thermocouple should be chosen for a furnace operating at around 1000°C?
Thread Content
The operating temperature of the furnace is around 1000°C – which type of thermocouple should be used? Is a K-type thermocouple suitable?
The manufacturer’s equipment specifications state that K-type thermocouples refer to nickel-chromium/nickel-silicon thermocouples and nickel-chromium/nickel-aluminum thermocouples, with a temperature range of -200 to 1300°C; so 1000°C should be within the range covered by K-type thermocouples
K-index division is feasible; choose a better protection tube. Wuxi Hanle Technology specializes in the production of thermocouples in various specifications, which are provided for free use.
Type B thermocouples should be chosen; of course, this doesn’t mean that Type K thermocouples can’t be used either, as they are cheaper
Platinum wires are too delicate; in my experience, K wires can last for several months. They are inexpensive, and it’s much more cost-effective to replace three of them per year rather than using precious metals
What furnace? What medium is inside? What’s the pressure? All of these are very important.
The gases in the furnace chamber are quite complex, so it is important to choose the appropriate sleeve.
The maximum operating temperature for K-type thermocouples is 1000 degrees on a long-term basis, and up to 1200 degrees in the short term; therefore, it’s fine to use the K scale here. Of course, if money isn’t a concern, one can choose a higher temperature scale as well. Hehe~~
