  • Patent number: 10584959
    Abstract: A FBG strain sensor arrangement includes a sensor carrier of steel sheet to which a FBG strain sensor is fastened. A protective cover has a first part configured thin and narrow and bonded to the sensor carrier along an optical fiber so that the optical fiber lying underneath is fixed with a fiber Bragg grating on the sensor carrier. The protective cover is enlarged at each end portion of the optical fiber to thereby form a cavity underneath, with edges of the enlarged second part of the protective cover being bonded to the sensor carrier. Arranged in the cavity is an elastic filler which embeds the coupling points in a vibration damping manner. The protective cover with elastic filler accommodates thermal expansions and functions for dynamic measurements by the vibration damping.

  • Patent number: 10502553
    Abstract: A weldable strain sensor includes a strain sensor having two end portions in signal communication with signal lines for transmitting a measurement signal. A sensor carrier extends in a direction of the strain sensor and is firmly connected to the strain sensor. The sensor carrier includes two end portions having slots to thereby form tongues defining tongue ends which are directed in opposition to each other. Integrally surrounding the strain sensor and the end portions thereof is a protective cover of solid plastic which is firmly connected to the sensor carrier. The protective cover is configured in a region of the strain sensor narrow and flat and in a region of coupling points of the strain sensor with the signal lines at least twice as wide and at least twice as high as in a region of the strain sensor.

  • Publication number: 20190277627
    Abstract: A FBG strain sensor arrangement includes a sensor carrier of steel sheet to which a FBG strain sensor is fastened. The FBG strain sensor includes an optical fiber having two end portions, with a Bragg grating provided between the end portions. An optical signal line is coupled to each end portion for transmission of a measurement signal. A protective cover has a first part configured thin and narrow and bonded to the sensor carrier along the optical fiber so that the optical fiber lying underneath is fixed with the Bragg grating on the sensor carrier. The protective cover is enlarged at each end portion of the optical fiber to thereby form a cavity underneath, with edges of the enlarged second part of the protective cover being bonded to the sensor carrier.

  • Patent number: 10132700
    Abstract: An FBG strain sensor for measuring strains to curved surfaces, includes a fiber which is fixed between two securing elements whose undersides are designed as adhesive surfaces, the optical fiber and these securing elements being embedded in a protective compound which consists of a soft silicone rubber or a plastic that has comparable mechanical properties, and the fiber being embedded between an upper and a lower thin sliding film or a sliding tube that consists of Teflon or of a plastic which has a low friction coefficient comparable to Teflon, the underside of the lower sliding film or the lower external surface-line of the sliding tube lying in a plane with the adhesive surfaces of the securing elements.

  • Publication number: 20130265564
    Abstract: The invention relates to an optical strain gauge (1) using a glass fibre as a strain sensor. The strain gauge comprises a glass fibre comprising a sheath. The sheath has the following composition: a mixture of polyether ether ketone and an admixture of at least 10 weight percent and a maximum of 40 weight percent of an inorganic filler, with a particle size of between 0.08 ?m and 12 ?m. The outer diameter of the sheath is between 0.2 mm and 1.2 mm. The ratio D/d between the outer diameter D of the sheath and the diameter d of the glass fibre is between 2 and 6. A pressure of the sheath on the glass fibre is such that essentially no relative movement can occur between the glass fibre and the sheath.
