Part 1 of this series took a close look at thermocouples. This part will look similarly at RTDs. After a review of the basic construction of an RTD, we will take look at an RTDs Temperature Coefficient of Resistance (TCR), its sensitivity, accuracy, interchangeability, repeatability, stability and drift, corrosion and contamination effects, shock and vibration effects, insulation resistance, lead-wire resistance, self-heating effects, meter-loading, packaging and thermal transfer considerations, response time, and thermoelectric effects. In part 3 of this series, we will summarize and compare the thermocouple and RTD sensor types, and provide information for selecting the best sensor for a given application.
