AP Sensing’s Distributed Temperature and Strain Sensing (DTSS) technology provides critical insights into the structural health of railway infrastructure, including bridges, tunnels, and tracks. Using Brillouin-based Optical Time Domain Reflectometry (OTDR), DTSS continuously monitors temperature and strain changes along fiber optic cables, precisely detecting anomalies such as mechanical stress, structural shifts, and thermal variations.

Ideal for railway monitoring, DTSS enables early detection of risks like landslides, track deformations, and tunnel instability, enhancing safety and minimizing disruptions. Immune to electromagnetic interference and requiring minimal maintenance, DTSS offers a cost-effective, reliable solution for proactive railway infrastructure management.
