This project pioneers Rayleigh-based distributed temperature sensing in hollow-core fibres, enabling breakthroughs in monitoring subsea cables, wind farms, and nuclear systems, while combining simulation, experimentation, and cutting-edge optical technologies. The Sensornet team will design the entire engineering solution for you. This includes the fibre optic DTS cable and its installation, associated accessories required such as inwell components (splicing, housing) and termination and junction boxes, the distributed temperature sensing equipment and. Distributed temperature sensing (DTS) measures temperature distribution over the length of an optical fiber cable using the fiber itself as the sensing element. Unlike traditional electrical temperature measurement (thermocouples & RTD), the length of the fiber optic cable is the temperature. The backscattered light returning to the measurement box is analyzed to produce a temperature measurement every meter down the fiber. At the Optoelectronics Research Centre. Fiber optic temperature sensors are immune to the many environmental effects that compromise other measurement technologies, can be embedded and installed in locations traditional temperature sensors cannot and deliver an unprecedented level of spatial detail and data without sacrificing precision. The distributed fiber optic measurement systems consist of a special optical interrogator and fiber optic sensor cables with a coating which is best adjusted to the installation on the structure. Large structures can be monitored with fibre optic sensors.
