Abstract: 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.

Abstract: The invention relates to an optical sensor device comprising a reference body, an optical fiber including an intrinsic fiber optic sensor, and a hydraulic transmission system. The hydraulic transmission system is connected to the reference body such that an input portion and an output portion are movable with respect to the reference body. The optical fiber is connected with a first connecting portion to the output portion of the hydraulic transmission system and with a second connecting portion to an element exterior to the hydraulic transmission system. The intrinsic sensor is positioned between the first and second connecting portion. The input portion is arranged for receiving an input action and the hydraulic transmission system is arranged for converting the input action to a sensing action applied to the optical fiber by the output portion such as to modify strain in the optical fiber dependent on said input action.

Abstract: 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).

Abstract: The invention relates to an optical sensor device comprising a reference body and at least one sensing transducer. The sensing transducer is arranged for receiving an input action, and is movably arranged relative to the reference body for moving relative to the reference body in response to the input action. The device further comprises an optical fiber and one or more transmission arms including a first transmission arm. The optical fiber comprises an intrinsic fiber optic sensor. The optical fiber is connected with a first connecting part thereof to the first transmission arm and with a second connecting part thereof to an element exterior to said first transmission arm. The first connecting part and the second connecting part are on either side of the intrinsic fiber optic sensor. For receiving the input action, a base of the first transmission arm is connected at a first part thereof with the reference body and with a second part thereof with the sensing transducer. The optical fiber is connected at a location along the first transmission arm remote from the base thereby converting the input action received by the sensing transducer into a sensing action applied to the optical fiber such as to modify strain in the optical fiber dependent on said input action.
