The Article Discusses an Overview of What is a RTD Sensor. Working Priniple of RTD, Sensor Applications, and Its Examples What is an RTD? RTD (Resistance Temperature Detector) is a temperature sensor whose resistance changes as its temperature changes, with resistance increasing as the sensor’s temperature rises. RTDs are typically made from pure platinum, which provides high accuracy, stability, and repeatability across a wide temperature range. These sensors are widely used in industrial, scientific, and laboratory applications where precise temperature measurement is critical. An RTD or resistance thermometer stands for resistance temperature detector that is used for measuring the change in temperature by measuring the variation in resistance over the temperature range. Probes, Sensors or elements used to measure temperature by correlating the resistance of the RTD element with temperature.
