Analysis of the distributed temperature sensor (DTS) measurements determined the most appropriate optical fiber to be used in high temperature industrial environment over long periods of time. To demonstrate the feasibility of this DTS for an industrial application, an optical cable was designed with the appropriate optical fiber and it was hermetically sealed to provide the required mechanical resistance and isolate the fiber from environmental degradations. This cable was used to measure temperature up to 360 °C of an industrial furnace during 7 days.}, organization = {This work has been supported by the Spanish Government through the Ministry of Economy and Competitiveness project TEC2016-76021-C2-2-R, AEI/FEDER (UE) and ENSA through the FACON project.}, publisher = {MDPI}, publisher = {Sensors, 2019, 19(3), 574}, title = {Comparative experimental study of a high-temperature raman-based distributed optical fiber sensor with different special fibers}, author = {Laarossi, Ismail and Quintela Incera, María Ángeles and López Higuera, José Miguel}, }
