Abstract

This paper presents a monitoring temperature system in real time. The fluoroptic temperature could be detected quantitatively by the signals of PSD. When the optical fiber is 2 m long, the real-time temperature sensitivity is 0.1 degrees Celsius and the accuracy is 1%. The high sensitivity and high accuracy are partly due to the operation of the light source feedback, and partly due to the ratio of measurement and reference signals. This fluorescence temperature measuring system finds wide application fields where conventional techniques either cannot be used, or have proven to be unsatisfactory. It is especially useful for measurements in electrically hostile environments.
