Calculators for Platinum RTD's

With this calculator you can convert temperature values into the corresponding resistance values of Platinum RTD's. Simply prompt the temperature and click on "Calculate"



At the prompted temperature the Sensor has


Formulas used for conversion (acc. to DIN IEC 751)

For the range -200...0 °C :
R [Ω] = Pt [ 1 + 3,90802 ·10-3 · t - 0,580195 ·10-6 · t2 - 4,27350 ·10-12 · ( t - 100 ) · t3 ]

For the range 0...850 °C:
R [Ω] = Pt ( 1 + 3,90802 ·10-3 · t - 0,580195 ·10-6 · t2 )

R = Resistance in Ohm
Pt = Base value (Zero degree value) e.g. for Pt100 = "100"
t = Temperature
