A platinum resistance thermometer is calibrated at two fixed points of the ITS-90, namely at the triple point of water (T1=273,160 K, R = 100,500 2) and at the melting point of tin (72=505,078 K. R = 193,730 92). Afterwards, it is used to determine the temperature in a measuring cell in which it has a resistance of Rmeas = 151,489 92. a) Calculate the temperature Timeas inside the measuring cell b) How accurately must the resistance Rmens be measured if the contribution of the resistance measurement to the uncertainty of the temperature measurement should be less than 3mK? c) Why are platinum resistance thermometers usually calibrated at more than two fixed points?
