We at NBG develop cutting edge technology for contemporary monitoring systems. With our analyse tools you can monitor structures from anywhere in the world. On this page you can read more about our advanced systems.
Monitoring the structural integrity of civil infrastructures is called Structural Health Monitoring (SHM) and is nowadays more and more important issue to reduce the cost of ownership. The primary function of monitoring is to ensure the safety of the structure, as well as to optimize its maintenance. Our SHM monitoring system is based on Fiber Bragg Grating (FBG) technology and brings many advantages over the conventional sensing methods, making health monitoring of large structures easier.
The FBG has great characteristics of their multiplexing capability and self-referencing. This means that several sensors, with different functions, can be connected in series on a single fiber without signals being confused and with necessary cable length becoming considerably smaller. The connection between unit and sensors is ensured via standard telecommunication fibers. A distance between unit and sensors can be up to several tens of kilometers. Therefore you can cover a large area with one unit and lots of sensors.
Being the measurement for each grating a reflected wavelength, which is an absolute parameter, there is the possibility of turning off or changing the measurement unit without the need to calibrate or determine a new zero.
