Different between Rtd & thermocoupler? And his type work.

Question

Accepted Answer

RTD measures temperature using the resistance change of a metal, while thermocouples measure temperature using the voltage generated at the junction of two different metals.

RTD stands for Resistance Temperature Detector, while thermocouple is a temperature sensor made of two different metals.
RTDs are more accurate and stable compared to thermocouples.
RTDs have a linear relationship between resistance and temperature, while thermocouples have a non-linear relationship.
RTDs are typically used in applications where high accuracy is required, such as laboratory settings, while thermocouples are used in industrial applications due to their durability and wide temperature range.
Example: RTD - Platinum RTD, Thermocouple - Type K thermocouple.
