MERLIN NX IP AND MST/TP VAV CONTROLLER - INSTALLATION INSTRUCTIONS
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
