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)
