RTD Pt100 vs Thermocouple
It is not practical to compare RTDs (Pt100 and others) and thermocouples generally. However, if we compare their performance in terms of specific criteria, we can see which is best suited for specific applications. Thermocouples are best for working at high temperatures. New manufacturing techniques have improved the measurement range of RTD probes, but more than 90% of RTDs are designed for temperatures below 400°C.
In contrast, some thermocouples can be used at up to 2500°C. Thermocouples are generally cheaper than RTDs...
Understanding Thermocouple Accuracy Drift
One constant in industrial processing is that accuracy drift in a measurement device is something to be avoided. For critical applications, where temperature measurements directly influence performance, even a slight drift in the accuracy of a device like a thermocouple can lead to significant issues.
Yet, consumers continuously find that many of the thermocouples out there on the market end up needing to be recalibrated or replaced all together (sometimes after an annoyingly short period of time) due to, you guessed it, accuracy drift.
