No, the layout of the equation is the same (as shown below) but the constants A, B and C differ from RTD to RTD.
Callendar Van Dusen equation:
R(T) = R0(1 + AT + BT2 + C(T - 100)T3)
Where
T = temperature (degrees C)
R(T) = resistance at T
R0 = resistance at T = 0 degrees C
Where constants A, B, and C are derived from experimentally determined parameters α, β, and δ using resistance measurements for each made at 0 °C, 100 °C and 260 °C.
These constants vary from RTD to RTD.
