Testing of luminescence fiber optic temperature measuring system

摘要

In the paper testing and investigation of temperature luminescent fiber optic sensors were presented. The main characteristic domain of fiber optic sensors are the non sensitivity to strong electromagnetic disturbance radiation, the complete galvanic insulation as well as the full safety their using in places endangered of explosions and a risk of fire. For this reason fiber optic sensors may chance to be the interesting and valuable completion of electric and electronic sensors for industrial and scientific application. There are group of luminescent materials, which after their excitation, emit the own light and the properties of emitted light depend on temperature. On temperature depends spectrum of light, its intensity and dynamic parameters of light decaying after excitation. These effects have found application in sensor techniques. We have elaborated fiber optic temperature sensors based just on dependence of decaying time on temperature. These sensors are planed to applied in high power transformers and power machines for their work state control.
