| Abstract: | In This paper, design and realization of a high performance platinum resistance thermometer are introduced. Four - wire resistance measurement is used to eliminate the influence of wire resistance, and digital calibration is also used to decrease error in transform from resistance to temperature to reach a high precision . This thermometer can operate under industrial environment. It has been used in our distributed fiber temperature sensor , and reached a excellent effect. |
