Note! - there are also PT1000 sensors with resistance 1000 ohms at 0 °C.
The linearization equation for the Pt100 thermometer is
Rt = R0 (1 + A t + B t2 + C (t - 100) t3) (1)
Rt = resistance at temperature t (ohm)
R0 = resistance at temperature 0oC (ohm)
t = temperature (oC)
A = 3.9083 10–3
B = –5.775 10–7
C = –4.183 10–12 (for temperatures below 0oC)
C = 0 (for temperatures above 0 °C)
