Exercise 4 Temperature Coefficient of Resistance (TCR), a of RTD is given by formula; R100 - Ro Rox 100 where R100 = resistance of RTD at 100°C, Ro= resistance of RTD at 0°C. αo and the relationship between resistance and temperature can be expressed as; Rt = Ro (1 + αot) where Rt = resistance of RTD at temperature t°C. If a platinum RTD measure 11002 at 0°C and 142.50 at 100°C, Calculate; i. The TCR of the RTD ii. The resistance of RTD at 70°C iii. The temperature when the resistance is 120°C
