They detect temperature hotspots, cable faults, and third-party intrusions, ensuring efficient load management, preventing outages, and enhancing the reliability of power transmission systems. Distributed temperature sensing systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. Unlike traditional electrical temperature sensors (e. These fiber optic systems precisely measure the temperature profile of an asset by interpreting the. Optical fiber-based temperature sensors have played a crucial role in this decade to detect high fever and tackle COVID-19-like pandemics. Depending on the application and the used technology standard fiber optic telecom cables are suitable, while other applications may. High-temperature measurements above 1000 °C are critical in harsh environments such as aerospace, metallurgy, fossil fuel, and power production.
