The operation of Resistance Temperature Detector (RTD) is based on the fact that the electrical resistance of the detector material changes with temperature. For Nickel which is sometimes used in such detectors, the resistance, RT at temperature T(⁰C) as a function of temperature is given by: RT=R₀(1+AT+BT²+CT⁴+DT⁶) where Ro us the resistance of the detector at 0°C and A=5.485 x 10⁻³, B=6.65 x 10⁻⁶, C=2.805 x 10⁻¹¹and D=-2 x 10⁻ ¹⁷ are constants. Consider a detector with Ro= 100Ω and determine the temperature when the resistance is 300Ω.
