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.

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.

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.

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.

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.

The slave digital terminal can access the protected data only if information necessary for accessing the data and received by the master digital terminal is sent by way of link (3) to the slave digital terminal within a predetermined deadline. This information is in particular access entitlements to television services or keys for descrambling the service.

Abstract: The stator shroud is made up of components (2) juxtaposed so as to form circumferences, which are successive and assembled separately to a common housing which surrounds them. Characteristically, the assembly is made with only one single fixing point (7) per component (2), while being completed by a support point (21) sliding along the circumference. The result is a more flexible component assembly and a more even distortion, which allows better control of the clearances between the shroud and the rotor blades it surrounds.
