    摘要: A sensor assembly comprises an optical fiber having a sensing fiber portion that comprises at least one Fiber Bragg Grating. Further, the sensor assembly comprises a sensing body having body ends coupled to the fiber at opposite axial sides of the sensing fiber portion. Optionally, the optical fiber is arranged within a capillary, and the body ends of the sensing body are attached to the capillary, at opposite axial sides of the sensing fiber portion. The capillary may be filled with glue for attaching the optical fiber to the capillary.

    摘要: The embankment monitoring system comprises an optic sensor chain (10) and an interrogator (20). The optic sensor chain (10) comprises a series of intrinsic fiber optic sensors (12) that are mutually spaced with respect to each other in a longitudinal direction of the optic sensor chain and at least one optic fiber (14) to optically connect the plurality of intrinsic fiber optic sensors to the interrogator. The interrogator is configured to issue an optic interrogation signal and the intrinsic fiber optic sensors are configured to respond to the optic interrogation signal with an optic measurement signal that is indicative for at least one physical parameter (P1) sensed by the intrinsic fiber optic sensors. The interrogator is further configured to process the optic measurement signals of the intrinsic fiber optic sensors to estimate a depth (d) as a function of a position (p) along said optic sensor chain (10).

    摘要: The present document relates to a pressure sensor comprising a structural element, the structural element comprising a first and second structural part. The sensor further comprises a first cavity being in fluid connection with an exterior of the sensor for establishing a first pressure which is dependent on an external pressure in the first cavity and a second cavity configured to be at a second pressure in use. A deformable structure is deformable dependent on a pressure difference between the first pressure and the second pressure. The sensor comprises a fiber including an intrinsic fiber optic sensor fixed to the structural element and to the deformable structure for providing an optical sensor signal dependent on said pressure difference.
