Answer:
RTD vs Thermocouple. ... In contrast, certain thermocouples can be used to measure up to 2700 degrees Fahrenheit. RTDs are superior to thermocouples in that their readings are more accurate and more repeatable. Repeatable means that users reading the same temperatures produce the same results over multiple trials.

Answer:
1. The starring difference between RTD and thermocouple is the operation principle and manufacturing.
2. RTD provides reliable output over a period. The calibration of the RTD outcome is much easier than other measurements.
3. Thermocouple offers a wide range of accuracy, particularly at elevated temperatures, making it difficult for a reliable output.
