FOSA Case Studies & Papers
Fiber optic sensing examples and technical papers.
In parallel with the launch of Doha Metro operations, AP Sensing’s industry-proven Linear Heat Detection (LHD) system began monitoring Doha Metro’s railway tunnels using Distributed Temperature Sensing (DTS) technology. A total of 128 km of the tunnel network is monitored by 16 multi-channel DTS units and 132 km of fiber optic sensing cable. Our system integrates seamlessly with FACP and SCADA systems such as the Train Management System, generating thousands of temperature readings with a 1 m spatial resolution.
