AP Sensing is a leading German provider of Distributed Fiber Optic Sensing (DFOS) solutions for monitoring tram and train infrastructure. Utilizing Distributed Acoustic Sensing (DAS), Distributed Temperature Sensing (DTS), and Distributed Temperature and Strain Sensing (DTSS), AP Sensing transforms a single fiber core into a continuous, real-time sensor. This enables a 100% maintenance-free, passive track setup for capturing tram and train movement data, detection of track condition issues, wheel-rail contact zone defects, intrusion monitoring, cable theft and vandalism protection.

Product description

Distributed Acoustic Sensing (DAS): • Accurate detection and location of moving trains • TPI monitoring and detection • Asset monitoring of tracks and moving stocks • Real-time algorithms and AI technology Distributed Temperature Sensing (DTS): • Continuous temperature monitoring along the fiber optic cable • Heat/fire detection and location in cable ducts, cable trays, metros and train stations • Full set of certifications (UL, ULC, SIL2, IQNet, ILAC-MRA) Distributed Temperature and Strain Sensing (DTSS): • Continuous strain monitoring along the fiber optic cable • Increased static and transient strain along structures like bridges • Monitoring range of 80 km • Positional accuracy of 2 m
