Temperature Measurement via Optical Cable in Thermal Pipelines

Distributed Temperature Sensing (DTS) systems provide temperature information for accurate thermal monitoring, fire detection, and condition assessment by utilizing standard fiber optic cables. This paper reviews the sensing principle, structural design, and. Distributed temperature sensing (DTS) measures temperature distribution over the length of an optical fiber cable using the fiber itself as the sensing element. Initiated in the 1980s, DTS systems have undergone sig-nificant improvements in the technology. [pdf]
