Mean temperature coefficient between 0 and +100C = 3.85 x 10-3 x K-1 (in accordance with IEC 751,2: 1995-07 resp. DIN EN 60751: 1996-07)

Calculation of resistance values:
Equations acc. To IEC 751,2: 1995-07 resp. DIN EN 60751: 1996-07:

Temperature range from -200 to 0C:
Rt = Ro {1 + At + Bt2 + C(t -100C) t3}

Temperature range from 0 to +850C:
Rt = Ro (1 + At + Bt2)

Where:
A = 3.9083 x 10-3 C-1

B = -5.775 x 10-7C-2

C = -4.183 x 10-12C-4

Rt is the resistance in at temperature t

t is the temperature in C

For nominal resistances 100 at 0C, resistance values from the table are multiplied by the factor:
Ro x 10-2 (Ro = nom. Resistance at 0C).

    PERMISSIBLE DEVIATIONS FROM THE REFERENCE TABLES  
       
   

The permissible deviations for platinum resistance elements are determined by the following equations (in accordance with IEC 751,2: 1995-07 resp. DIN EN 60751: 1996-07):

Permissible deviation in C = ± (0.15 + 0.002 {t}) for Class A

Permissible deviation in C = ± (0.3 + 0.005 {t}) for Class B

Where {t} is the temperature value in C.

Deviations in C apply to all nominal resistances. Deviations in apply only to 100 .

For nominal resistance values other than 100, the deviation values in must be multiplied by the factor Ro x 10-2

More restricted or wider tolerances can be supplied on special order.
