Nominal values
The nominal or rated value of the sensor is the target value of the sensor resistance at 0° C. The temperature
coefficient
α is defined
as
α =
[K
-1] and has the numerical value of 0.00385 K-1 according to DIN IEC 751.
In practice, a value multiplied by 10
6 is often entered: TCR = 106 *
[ppm/K].
In this case, the numerical value is 3850 ppm/K.
Temperatur Characteristic Curve
The characteristic temperature curve determines the dependence of the electrical resistivity on the temperature.
The following definition of the temperature curve according to the DIN EN 60751 standard applies:
-200 bis 0°C
R(t) = R0 (1 + A * t + B * t
2 + C * [t-100] * t3)
0 bis 850°C
R(t) = R0 (1 + A * t + B * t
2)
Platinum (3850 ppm/K):
A = 3.9083 * 10
-3 [°C-1]; B = -5.775 * 10-7 [°C-2];
C = -4.183 * 10
-12 [°C-4]
Platinum (3750 ppm/K):
A = 3.8102 * 10
-3 [°C-1]; B = -6.01888 * 10-7 [°C-2];
C = -6 * 10
-12 [°C-4]
Platinum (3770 ppm/K):
A = 3.92 * 10
-3 [°C-1]; B = -6.03 * 10-7 [°C-2];
R0 = Resistance value in ohm at 0°C;
t = temperature in accordance with ITS 90
Tolerance Classes
temperature sensors are divided into classes according to their limit deviations:
