Study on the Fiber Optic Sensor Installation Used in Distributed Temperature Sensing System for Belt Conveyor Monitoring System

This paper presents the study on the distributed temperature sensing system (DTS) to determine the factors affecting the optical fiber thermal sensor and develop more accurate temperature sensors adapted for installation in work operating all the time and has a long distance is a belt conveyor system. The fiber optic thermometer uses the principle of Raman scattering. The performance of the fiber optic sensor was tested under various tests. Sensor cartridge structure was designed and made from steel and aluminum to test the properties, Number of fiber optic roll in the cartridge, the distance effect, and the ground environment. The results showed that cartridge materials affect heat transfer, and the installation distance between the fiber optic sensor and heat source should be at most 15 cm. Number of fiber optic roll in the cartridge was accurate when increasing number of rolls. The ground environment was also an essential factor to consider for improving the DTS system in the belt conveyor system.
