FBG SENSORS
Our sensors are available in several sizes and shapes. Here is a selection of our products, but ask for different models.
QP-FBG sensor is a very lightweight and highly flexible sensor in a composite material package developed by the Aerospace Engineering Department of Politecnico di MIlano.
It has been optimized for embedding in composite structures for aerospace applications, but it offers excellent performance even in case of surface bonding for deformation and/or vibration detection.

LG-FBG sensor is a long gauge sensors for civil structural monitoring.
It is available for wall mount and for embedding in concrete.
It is provided with a pre-loading system which allows the FBG sensor to work in elongation and shortening, so to detect both tensile and compressing strain or bidirectional displacement.
