Picture 1: Resistance and temperature tolerances of CPT 1000 B
Temperature range of -50 °C up to 0 °C:
Rt = Ro · (1 + A · t + B · t² + C · (t – 100 °C) · t³)
Temperature range of 0°C up to 150°C:
Rt = Ro · (1 + A · t + B · t² )
Tolerance class B to DIN EN 60751:
∆t = ± (0.3 + 0.005 · | t |)
Whereby:
Rt … Resistance [Ω] at temperature t
Ro … Resistance [Ω] at 0 °C
t … Temperature [°C]
∆t … Permissible temperature deviation at t [°C]
A = 3.9083 · 10^-3 °C^-1
B = - 5.775 · 10^-7 °C^-2
C = - 4.183 · 10^-12 °C^-4
