Monitoring solution based on the optical FBG technology
By using fiber Bragg grating (FBG) technology, the company was able to deliver a competitive solution when compared to the alternative proposals based on conventional technologies.
Monitoring solutions based on the optical FBG technology have proven to be cost effective when applied to large scale structures (tunnels, bridges, dams, pipelines, etc.) where hundreds of sensors are deployed over more than ten km and connected by few fibers to a central interrogator for structural health monitoring.
This large project involved HBM technical teams from Austria, Germany and Norway as well as HBM FiberSensing (HBM business subsidiary in Portugal) technicians to work together in the deployment of hundreds of optical sensors in an extreme and confined environment.
