This free, online technical paper from Burns Engineering discusses why the resistance at the triple point of water (RTPW) is considered the most important piece of information obtained during calibration of a Secondary Standard Platinum Resistance Thermometers (SSPRT). It goes further, telling how the change in the RTPW can be used to estimate changes at [...]
RTD
Platinum Resistance Thermometers (PRTs), a subgroup of Resistance Temperature Detectors (RTDs), are are far more precise than thermocouples and more nearly measure at a point, rather than along their length. They, however, have limitations and there are specific error sources to be considered in specifying and engineering an installation of one or more devices. Burns [...]
