Aiming at difficult problem of reactor temperature detection

a kind of wireless temperature measurement system is designed by using fiber Bragg grating（ FBG） temperature sensor. Temperature change curve of reactor wrappage for 6 h is obtained by experiment. The results show that the system can fully reflect internal temperature distribution

judge trend of temperature change and determine specific location of abnormal temperature point

provide important reference for the timely detection of failures and to ensure stable and reliable operation of the reactor.
