Fluorescence Based Fiber Optic Temperature Sensors

Fluorescence based fiber optic monitoring system conducts real time monitoring to accurately measure temperature of transformer’s winding hotspot and switchgear contact points. It is a single point temperature sensor. It is suitable for work in harsh environment like high pressure, high temperature and strong electromagnetism. The size of fiber sensor is very small and it can be easily installed on measuring point with high measurement accuracy and high response frequency.

In this technology rare-earth fluorescent material is formed at the tip of the optical fiber. The other end of the fiber is attached to a light source. The light source is used to excite the fluorescent material. After excitation, the fluorescent material tends to return to its ground state by emitting a photon (light). The time taken to return to ground state varies according to temperature.
