Process Engineering Section – Instrumentation and Automation Section – Daily Question – Question from 2020-07-31: Discussion question: 192. Among the three types of thermocouples with scale numbers S, K, and E, which one has the highest potential at 100 degrees Celsius? Which one is the smallest?
At 100 degrees, the electromotive force of scale number S is 0.645 mv； At 100 degrees, the electromotive force for division number K is 4.095 mv ； At 100 degrees, the electromotive force of division E is 6.317 mv. Therefore, E has the highest thermoelectric potential, K is next, and S has the lowest.

Therefore, E has the highest thermoelectric potential, K is next, and S has the lowest.
The maximum E division is 6.317 mV, and the minimum S division is 0.645 mV.
At 100 degrees, the electromotive force of the S type is 0.645 mv; at 100 degrees, that of the K type is 4.095 mv; and at 100 degrees, that of the E type is 6.317 mv. Therefore, E has the highest thermoelectric potential, K is next, and S has the lowest.
