Among temperature sensors, it is the most stable and accurate sensor. It has a better repeatability, and shows more dependable outputs than thermocouple. It is possible to perform an area measuring, and has a better resistance against the containment. However, it has a slow response time due to its complexity of the resistance element and its big size. It is constructed with an insulated lead wire and with protection tube which is designed to protect the insulated lead wire.
