Distributed temperature sensing (DTS) is a fiber optic technology that uses a standard fiber optic cable as a sensor to measure temperature continuously along its entire length. It works by sending a laser pulse down the fiber and analyzing the backscattered light, which is affected by temperature. This allows for continuous, high-resolution temperature profiles along assets like power cables, pipelines, and tunnels, providing real-time monitoring for applications like fire detection and condition assessment. It is being considered for MSSS where fibre optic cables are placed vertically within the waste bed. The aim is to use the resulting temperature profiles to infer the level of the liquor with high spatial resolution.
