RTD (Resistance Temperature Detector)

An RTD, or Resistance Temperature Detector, is a sensor that measures temperature by correlating the resistance of a pure platinum element with the temperature. Loved for their high accuracy and stability, they are a cornerstone of process control where dependable readings are non-negotiable.
