Abstract: A methodology for selecting and properly placing foil strain gages on a transducer in a Wheatstone bridge, which provides a more consistent creep response, especially when the transducer temperature is changed. A transducer includes a counterforce subjected to a predetermined physical load that provides tension and compression strains (positive and negative, respectively). The transducer also includes a plurality of strain gage grids that are operatively attached to the counterforce in the tension and compression strain areas of the counterforce and generate electrical signals. The plurality of strain gages are electrically connected in a Wheatstone bridge circuit where their electrical signals due to creep are cancelled.

Abstract: The invention relates to a measuring sensor with a deformation body (7) on which at least one strain gage (2) is applied. In that regard, the strain gage (2) is hermetically sealed against external environmental influences by at least one thin deep drawn metallic sheet metal part (4). This hermetic sealing sheet metal part (4) is preferably embodied bowl-shaped and consists of a high-strength hardenable corrosion-resistant spring steel of the maraging type with 7.8 weight % nickel, 13 weight % chromium, 1 weight % molybdenum, 0.2 weight % silicon, 0.3 weight % manganese, 0.25 weight % beryllium, 0.2 weight % titanium as well as the remainder iron, which surprisingly comprises only a small hysteresis and has at least equally good creep characteristics as the stainless martensitic spring steels of the deformation body (7). Due to the good weldability of the maraging sheet metal part (4) with the martensite deformation body (7), there arises a surprising utilization for the hermetic sealing of the sensitive strain gages (2), which cause neither a significant force shunt nor a worsening of the physical measuring characteristics.

Abstract: A force sensor with two force input elements to which a force to be measured and a support force are applied. The two force input elements are substantially rotationally symmetrical and are axially spaced apart, and the force to be measured and the support force are applied in radial directions. A spring element, arranged axially between the two force input elements connects these elements and its load-dependent deformation is converted into an electrical signal. A suppression of transverse forces is achieved in a purely mechanical manner so that the influence of transverse forces on the output signal of the force sensor are negligible. Both force input elements are additionally connected to each other by a guide element which encloses the spring element and which has two parallel guide connectors. The guide element is softer in the direction of the force to be measured than in a direction perpendicular thereto.

Abstract: A flexure pivot in the form of a thin material connection formed as a result of adjacent material-free spaces is disclosed, as is a force-transfer mechanism for use in a force-measuring device, in particular a balance, containing at least one flexure pivot of the aforementioned type. The force-transfer mechanism has a stationary portion with a lever arrangement comprising at least one reduction lever and serving to transmit a force to a measuring transducer, and it further has at least one coupling element serving to introduce an input force into the lever arrangement, the coupling element being stiff against lengthwise deformation but flexible with regard to bending and having at least one thin material connection. The at least one lever is supported on the stationary portion and/or on a preceding lever by a flexible fulcrum pivot having a thin material connection. At least one thin material connection zone of a thin material connection is delimited by concave-shaped surfaces facing material-free spaces, and at least one of the material-free spaces delimiting the thin material connection zone has a shape that creates a constriction of the thin material connection zone.

Abstract: A load cell has internal cuts or grooves allowing increased the measurable strain on a load cell package increasing its ability to accurately measure lower weights while reducing the load cell's sensitivity to thermal shock. These cuts or grooves are rectangular slots with circular ends and run parallel to the load cell. The cuts or grooves are cut into the gage-hole producing ridges. The strain gauges are located on the middle ridge which is a thicker wall which reduces the temperature differences between the gauges, causing the cell to generate less output during a thermal shock. Not only is the output due to thermal shock smaller, but it lasts for a shorter period of time.
