Fiber-optic sensing system for distributed strain and temperature monitoring
Uninterrupted monitoring is essential to manage risks and maintenance of large structures. Where kilometers of concrete, steel or soil are to be monitored for the early signs of failure, distributed optical fiber sensors are a powerful and highly efficient tool.
With industry-leading accuracy, fibrisTerre’s unique digital BOFDA and BOFDR technology answers the demand for reliability in long-term monitoring of pipelines, power cables, railway lines and geotechnical infrastructure.
Two light waves, injected into an optical fiber from both ends, meet and make the fiber shiver (literally), creating an acoustic wave inside the fiber. Influenced by this acoustic wave, the light that arrives at the instrument carries information on the fiber’s speed of sound – and, consequently, on its strain and temperature.
The fTB 5020 system converts industry standard optical fibers (the same used in everyday telecommunications) into continuous, long-range strain and temperature sensors. Application-specific fiber-optic sensing cables allow for reliable and versatile implementation into earth and rigid structures.
The fTB 5020 is controlled by a remote or local PC or workstation via Ethernet. fTView, fibrisTerre’s powerful monitoring software, allows to configure, perform, display and manage measurements.
