Temperature to resistance equation
The relation between temperature and resistance is given by the Callendar-Van Dusen equation,
Here, RT is the resistance at temperature T, R0 is the resistance at 0 °C, and the constants (for a platinum RTD) are
Since the B and C coefficients are relatively small, the resistance changes almost linearly with the temperature.

For the range between -200 °C to 0 °C the equation is
R(t) = R(0)[1 + A(t) + B(t)2 + (t − 100)C(t)3].
For the range between 0 °C to 661 °C the equation is
R(t) = R(0)(1 + A(t) + B(t)2).
