A platinum resistance thermometer (PRT) is a transducer which measures temperature 0 by means of consequent change of electrical resistance RT between its
two terminals. Such a PRT has the following quadratic characteristic:
RT=Ro [1+A0+BO^2]
The PRT is calibrated so that its resistance is Ro = 100 Q at a reference temperature of 0 = 0°C.
The coefficients have the following values:
A = +4.0 x 10-3 °C-1
B = -5.0 x 10-6 oc-2
Determine sensitivity of this transducer at temperatures of +50 °C.
