With the launch of its 5th Generation of Distributed Acoustic Sensing (DAS), AP Sensing makes strides in asset monitoring technology with a system that, unlike traditional point sensors, provides gapless monitoring of valuable infrastructures such as pipelines, power cables, and railways.
The future of technology is here: standard fibre optic cables used as continuous sensors for asset protection and monitoring. AP Sensing’s 5th Generation DAS, specifically, utilises acoustic vibrations along the fibre optic cable in order to detect and precisely locate events in real time such as pipeline leaks, high voltage power cable faults, Third Party Interference (TPI) activities, or other abnormal events. Previous versions of this product boasted leading measurement capabilities, but the 5th Generation is also built for rapid adaptation to the asset environment, operation in harsh conditions and installation in remote environments. The 5th Generation DAS utilises unique detection algorithms to identify and locate critical events with improved detection sensitivity and reliability.
“Our R&D teams in both the UK and Germany spent years tirelessly developing our DAS technology and software,” says Dr Gareth Lees, CTO at AP Sensing. “The resulting product we have today shows a mature technology that can really be used to make a difference in protecting people and critical infrastructure everywhere.”
AP Sensing’s DAS system utilises Coherent Time Domain Reflectometry (C-OTDR) and Rayleigh backscattering to detect micro-vibrations and capture acoustic signals over long distances up to 100 km. In combination with smart classification algorithms, this technology can detect and locate events such as intentional or unintentional excavation above critical assets, or a pipeline leak to within a few meters. The new version of the product will be proudly used to protect and monitor assets 24/7 for many years to come.
