Res pt

Type Function: REAL

Input T REAL (temperature in °C)
R0 REAL (resistance at 0° C)
Output REAL (resistance)
RES_PT calculates the resistance of a PT resistance sensor from the input values T (temperature in °C) and R0 (resistance at 0°C).
The calculation is done using the formula
for temperatures > 0 °C
RES_PT = R0 * (1 + AT + BT²)
and for temperatures below 0 ° C
RES_PT = R0 * (1 + AT + BT² + C(T-100)
A = 3.90802E-3
B = -5.80195E-7
C = -427350E-12
The calculation is suitable for temperatures from -200.. +850°C.
