TRASDUTTORE PERFEZIONATO

Transducer (1) for the detection of strains and/or temperature variations in engineering works and/or terrestrial zones, the transducer (1) comprising at least one distributed optical fiber sensor (2) based on Brillouin scattering, wherein, for at least a part (22) of its longitudinal extension, said optical fiber (2) is housed inside a containment structure (20) which is destined to be associated with the engineering work and/or terrestrial zone of which, and along which, to detect the strains and/or temperature variations, wherein both ends of the optical fiber (2) are located outside the containment structure (20), said containment structure (20) comprising an intermediate layer (21) wherein said longitudinal part (22) of optical fiber (2) is completely contained and a pair of coating layers (6, 6') which cover above and below said intermediate layer (21), the mechanical stiffness characteristics of the coating layers (6, 6') and of the optical fiber (2) being substantially the same.
