FUNCTIONAL PERFORMANCE
The temperature resistance relationships of the PTS series
follow different equations:
For the temperature range of -55 °C up to 0 °C:
R
T
= R
0
x (1 + A x T + B x T
2
+ C x (T - 100 °C) x T
3
)
And for the temperature range of 0 °C up to +175 °C:
R
T
= R
0
x (1 + A x T + B x T
2
)
R
T
: Resistance as a function of temperature
R
0
: Nominal resistance value at 0 °C
T: Temperature in °C
According to IEC 60751 the values of the coefficients are:
A = 3.9083 x 10


B = -5.775 x 10
-7

The tolerances values of the PTS AT series are classified by
the following equations as specified by IEC 60751:
Class F0.3: T
F0.3
= ± (0.3 + 0.005 x |T|)
Class F0.6: T
F0.6
= ± (0.6 + 0.010 x |T|)
