RTDs - or Resistance Temperature Detectors - are temperature sensors that contain a resistor that changes resistance value as its temperature changes. They have been used for many years to measure temperature in a laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability.
4 wire connection is the most accurate measurement. The instrument measures the lead resistance of all four lead wires removing these values for its reading
