RTD stands for?

Explanation:
RTD refers to a temperature-sensing element that uses the change in electrical resistance of a material to determine temperature. The name describes exactly what it is: Resistance Temperature Detector. Platinum RTDs, such as Pt100 and Pt1000, are common because platinum offers a very stable and repeatable resistance–temperature relationship, providing accurate readings over a wide range. They’re often wired in 2-, 3-, or 4-wire configurations to compensate for lead resistance, which improves precision. The other options aren’t standard names for a resistance-based temperature sensor, making them less accurate as descriptors.
