Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors that use the electrical resistance of a substance (such as platinum) to measure temperature.

An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases.

RTDs, or resistance temperature detectors, are sensors used to measure temperature. These sensors are the among the most accurate temperature sensors available, covering large temperature ranges.
