Nickel Class B DIN 43760 Sensors
The characteristic of the nickel temperature sensor is
specified as per DIN 43760. The large Temperature
Coefficient of Resistance (TCR) of the Ni-RTD, 6178
ppm/K, offers greater sensitivity than other types of
RTD's. The electrical characteristic can be described by
the following equation:
R(T) = R0 (1+aT+bT2+cT4+dT6)
Coefficients:
• a = 5.485 x 10-3
• b = 6.650 x 10-6
• c = 2.805 x 10-11
• d =-2.000 x 10-17
T(R) = a´+b´(1+c´R)½ +d´R5+e´R7 dT < 0.12 K (higher order
equations on request)
Coefficients:
• a´= - 412.6
• b´= 140.41
• c´= 0.00764
• d´= - 6.25 x 10-17
• e´= -1.25 x 10-24
Tolerances:
• Class B (0.4+0.007 x |T|) in range from 32 °F (0
°C) to 320 °F (+160 °C) (0.4+0.028 x |T|) in range
from -67 °F (-55 °C) to 32 °F (0 °C)
