Resistance Temperature Detector (RTD)

A Resistance Temperature Detector (RTD) is a sensor used to measure temperature by exploiting the property that a metal's electrical resistance changes predictably with temperature. Typically made of pure metals like platinum, an RTD detects temperature by passing a small current through the metal and measuring the resulting resistance. As temperature increases, the metal's resistance increases as well. This resistance change is then converted into an accurate temperature reading. RTDs are valued for their precision and stability, making them ideal for industrial applications where accurate temperature monitoring is essential.
