Theory is closer to practice in theory than in practice. PT100 is 0,4 Ohm/K. Or 0.0000000004Ohm/nK. This means, at 100Ohm, you are measuring 4 parts per (ameri

PT100 is 0,4 Ohm/K. Or 0.0000000004Ohm/nK. This means, at 100Ohm, you are measuring 4 parts per (american) trillion for that nK.
Good Luck and please, report how many of those digits were pure noise!
- airbreather 4y agoInstrumentation engineer here, but RTD is not linear? Near linear but usually even for industrial use there is a three term polynomial correction applied. There's a whole standard devoted to the subject, DIN/IEC 60751.

- twawaaay 4y agoYeah, it is nonlinear and I did apply three term ploynomial correction as per manufacturers spec sheet.
