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: 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.
