Fiber Bragg Grating technology: the optimal solution
Fiber Bragg sensors measure physical quantities - such as strain - with light. In addition to its outstanding long-term stability, the technology offers another major advantage: It enables measured values to be transmitted over long distances, with virtually no loss in measurement quality. Furthermore, a single optical waveguide can accommodate several fiber Bragg sensors, thus reducing the effort needed to set up the monitoring system to a minimum. This is a crucial aspect, particularly when monitoring tunnels that often are many kilometers long.
"SysTunnel" from HBM FiberSensing is a special system solution enabling users to take full advantage of the benefits of using fiber Bragg sensors for tunnel monitoring.
