| Abstract | A new method for measuring the self-heating and response time of resistance thermometers is presented that can be applied to thermometers installed in situations where the temperature may be fluctuating and/or drifting with time. A technique developed for mass comparisons is used to analyse a sequence of ten indicated temperature measurements recorded with sensing currents I1 and I2 in the sequence (I1I2)5. Self-heating values are obtained with sub-millikelvin accuracy using standard equipment from self-heating changes of less than 1 °C. The response time of the installed resistance thermometer is obtained by repeating this sequence of measurements as a function of the delay between changing the sensing current and measuring the indicated temperature. |
