Process Engineering Division – Instrumentation and Automation Section – Daily Topics – Topic No. 2021-01-31: Discussion question: 374. What are the common type numbers of thermocouples used in your unit? What are the thermoelectromotive forces at 100°C?
K-type thermocouple, 4.095mv
At 100 degrees, K-type and S-type correspond to 4.1 mv and 0.6860 mv respectively
At 100 degrees, K-type and S-type correspond to 4.1 mv and 0.6860 mv respectively
K-type thermocouple, 4.095mv
It turns out that there were K-type thermocouples on the boiler, with a reading of 4.095 mV; now those thermocouples are no longer there, and PT100 thermistors are the only ones in use. . . .
