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. The resistance vs temperature relationship is well known and is repeatable over time.
Key Features

Linear change in resistance with temperature
Reliable performance in industrial and laboratory environments
Suitable for precise temperature measurement across wide ranges
Applications
Industrial process monitoring and control
Laboratory temperature measurement
