摘要： 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.

摘要： A device for measuring force and for monitoring wear on overhead lines includes a force-measuring system which includes two contact bars which, in an operating state, are oriented at a right angle to an overhead line to be monitored, and two connection bars, which, in the operating state, are oriented parallel to the overhead line. A bar-shaped force transducer is fastened to each end portion of the two connection bars and each of the bar-shaped force transducers extends in an axial direction of the respective connection bar.

摘要： A load cell has a longitudinal body including a bending beam axially between a force input element and a force output element, strain gages applied on strainable measuring parts of the bending beam, a hermetically sealed enclosure outside around the strain gages and the strainable measuring parts, and an overload protection arrangement including an overload beam in a recess in the bending beam, a receiving hole partially in the overload beam, and a fitting pin received in the receiving hole so that a defined gap is formed between the fitting pin and an adjacent stop surface in the recess of the bending beam. In further embodiments, the enclosure includes a stiff pipe sleeve and ring elements with flexible membranes connecting the sleeve to the longitudinal body, and a mounting end face of the longitudinal body has centering pins in holes and an O-ring in a groove.

摘要： A system for wirelessly supplying electric energy to a rotating device includes a flange disk, a disk-shaped ring, an annular plastic filling, a receiving coil which is embedded in the annular plastic filling, a U-shaped ferrite core having a short section, the end face of which is directed to the plastic filling, a long section which is oriented parallel to the short section and which extends parallel along the outer surface of the annular plastic filling, with the sections connected to one another via a section, a coil system and a receiving coil made of revolving wire windings. A distance of the end face of the long section from the rotation axis of the flange disk is smaller than a distance of the receiving coil from the rotation axis of the flange disk.

摘要： 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. Arranged in the cavity is an elastic filler which embeds the coupling points in a vibration damping manner.

摘要： A force transducer for measuring compression and/or tension forces includes a rod-shaped deformation body and at least four strain transducers applied on the deformation body and configured for measuring longitudinal and transverse strains thereof. Front and rear elongate recesses are provided on the front and rear sides of the deformation body in the area of an intersection between a central longitudinal axis and a central transverse axis of the deformation body. Left and right upper indentations and left and right lower indentations are provided on the deformation body respectively at the four quadrants bounded by the axes. A ratio of a cross-section on a center plane extending orthogonally to the central longitudinal axis and including the central transverse axis, to a sum of first and second partial regions of the cross-section, is from 1.56 to 2.15.

摘要： The present invention relates to a measuring amplifier (103) with background calibration and adjustment, as well as to a method for carrying out the background calibration and adjustment for such a measuring amplifier. The measuring amplifier amplifies, digitizes and processes at least one measurement signal (111) from at least one measuring transducer (102) with the aid of at least one amplifier arrangement (108). This can be intermittently replaced by an additional amplifier arrangement (107), which enables its interruption-free calibration and, if necessary, adjustment. In the calibration, both a zero point error as well as an amplification error of the amplifier arrangement are reliably determined. Moreover, the amplifier arrangement is calibrated directly and not indirectly. Thereby a high accuracy is achieved without measurement interruption. Furthermore, only one additional amplifier arrangement is generally required, even for a measuring amplifier with plural channels.
