  • Patent number: 7948341
    Abstract: A coil for an inductive sensor, such as a coil which is used in a sensor that operates according to the principle of electromagnetic force compensation for converting an amount of force generated by a load applied to a force-measuring cell into an electrical signal, is provided with protection against the penetration of moisture. The protection includes a protective covering with a surface-smoothing undercoating applied to the coil, on which a second level of coverage is applied as a protective coating against the penetration of moisture.

  • Patent number: 7516035
    Abstract: A method serves to correct drift phenomena, in particular creep effects, occurring in an electronic balance that has a measuring transducer through which a measuring signal is formed which is representative of a load applied to the force-measuring device. The measuring signal is delivered by way of an analog/digital converter to a signal-processing unit that is supported by at least one processor, said signal-processing unit being capable of compensating drift deviations, for which purpose the signal-processing unit, via the processor, accesses drift parameters that are stored in a memory unit and serve as basis for calculating a time-dependent correction value by which the drift error of the measuring signal (ms) is corrected.

  • Patent number: 7243558
    Abstract: In a force-measuring cell with a deformable body and with at least one strain gauge which has a strain-sensitive electrical resistor track arranged on a polymer carrier substrate, the strain gauge is bonded to the deformable body by an adhesive layer of an inorganic-organic hybrid polymer. For the bonding of the strain gauge to the deformable body, an adhesive compound having an inorganic-organic hybrid polymer in solution is applied to the deformable body, whereupon the strain gauge is placed on the hybrid polymer layer, and the adhesive layer is subsequently hardened at a temperature between 80° C. and 130° C. For the hardening of the adhesive layer, the deformable body with the strain gauge is exposed to the increased temperature for a time period between a half hour and three hours.

  • Patent number: 7215870
    Abstract: A strain gauge with a strain-sensitive electrical resistor track and connector electrodes for contacting the resistor track arranged on a carrier substrate is provided with a protective coating having inorganic materials and covering at least part of the carrier substrate and/or of the resistor track and/or of the connector electrodes. The build-up structure of the protective coating over the range of the coating thickness is inhomogeneous, and the protective coating is underlaid with a surface-smoothing polymer layer which evens out rough surface portions of the area to be coated. The layer thickness of the surface-smoothing layer is at least equal to the thickness of the protective coating. A strain gauge of this type can be used in a force-measuring cell, where the surface-smoothing layer and the protective coating can be deposited after an uncoated strain gauge has been installed on the deformable body of the force-measuring cell.

  • Patent number: 7197940
    Abstract: A multilayered coating is disclosed as a protective coating against moisture penetration for strain gauges that are or can be installed on a deformable body of a force-measuring cell. A strain gauge has a strain-sensitive electrical resistor track and connector electrodes for contacting the resistor track arranged on a carrier substrate, with a multilayered coating covering at least a part of the carrier substrate and/or of the resistor track and/or of the connector electrodes as a protective coating against moisture penetration. The multilayered coating is composed of an alternating sequence of a polymer layer and a barrier layer and consists of at least three thin individual layers. In the case where a multilayered coating is applied to a strain gauge that is already installed on the deformable body of a force-measuring cell, the multilayered coating can in addition also cover a part of the deformable body.

  • Patent number: 7155348
    Abstract: A force-measuring cell is disclosed which is equipped with a force transducer which includes a deformable body that is equipped with sensors. The deformable body connects a housing-mounted fixed part to a force-introducing part of the force transducer. The sensors are connected to electrical conductors of at least one flat ribbon cable which leads to a circuit module that serves to process the measuring signals and contains the connections for joining the sensors together in a measuring bridge circuit. The conductor tracks can be configured so that all of the connecting leads from nodal points of a measuring bridge to the contact terminals of the sensors have at least approximately equal resistance values.

  • Publication number: 20060169063
    Abstract: An exemplary mounting arrangement serves for the mounting of a force transducer that has a sensor-equipped core part connecting a support part to a force-application part. The support part can be bolted to a fastening part by mounting screws, and the force-application part can be bolted to a weighing pan carrier by means of mounting screws. The support part and the force-application part of the force transducer can each have a triplet of threaded holes serving to receive the mounting screws. Each triplet forms an isosceles triangle whose apex points towards the deformable body. The symmetry axes of the triangles lie in a plane that is parallel to the displacement travel of the force transducer. The mounting arrangement can be further configured to provide an effective overload protection in a low-profile design and to provide a thermally uncoupled fixation.
