I have four possible scenarios for making a type T thermocouple:
- use a 24AWG copper wire and a 24AWG constantan wire
- use a 20AWG copper wire and a 20 AWG constantan wire
- use a 24AWG copper wire and a 20AWG constantan wire
- use a 20AWG copper wire and a 24 AWG constantan wire
Based on the answer I received here, I'm under the assumption that I can mix and match different wire diameters (while holding wire material constant) without compromising the data since it is the Seebeck coefficient of the metal and not the resistance of the wire that determines how it operates as a thermocouple.
Will all 4 of these combinations give me accurate and similar data? If not, why?
