Method for distinguishing K-type S-type thermocouples

What is the difference between K-type thermocouples and S-type thermocouples?
K-type and S-type thermocouples are commonly used types of thermocouples, and their differences are mainly reflected in the measurement range and usage environment.
What temperature measurement ranges are K-type thermocouples suitable for?
The temperature range applicable to K-type thermocouples is -200 ℃ to 1250 ℃.
3. What temperature measurement ranges are S-type thermocouples suitable for?
The temperature measurement range applicable to S-type thermocouples is -50 ℃ to 1760 ℃.
How to distinguish between K-type thermocouples and S-type thermocouples through appearance?
Usually, the outer screen of K-type thermocouples is green, while the outer screen of S-type thermocouples is usually purple. They can be preliminarily distinguished by the difference in color.
5. How to distinguish between K-type thermocouples and S-type thermocouples through identification?
Generally speaking, the identification of thermocouples is engraved on their external screens, and identifying K-type thermocouples can find the word "K", while S-type thermocouples are marked with the word "S".
6. How to distinguish between K-type thermocouples and S-type thermocouples by wire color?
The wire colors of K-type thermocouples are usually green and white, while the wire colors of S-type thermocouples are mainly purple and white.
7. Comprehensive application of multiple methods
If the above methods cannot accurately determine whether it is a K-type thermocouple or an S-type thermocouple, you can also check the model of the thermocouple or ask professional staff to determine.
8. Precautions
When using thermocouples, attention should be paid to selecting suitable models and temperature measurement ranges to ensure measurement accuracy and reliability.
Through the above methods, we can distinguish between K-type thermocouples and S-type thermocouples, which can more accurately select and use thermocouples in practical applications to meet different temperature measurement needs.
