  • Patent number: 10036766
    Abstract: A method for producing a force-measuring element (10) having at least one articulation point (20) which separates one region of the force-measuring element (10) into two connected subregions (11, 12) which can be deflected in relation to one another. The method includes: providing a force-measuring element blank (10), removing material from the force-measuring element blank (10) in order to produce the articulation point (20), checking whether the deflection behavior of the subregions (11, 12) which is produced by the articulation point corresponds to a predefined specification, defining a correction form (30) which can be produced through material removal and compensates for an ascertained deviation from the predefined specification, correcting the articulation point geometry using a laser and the previously defined correction form (30), through material removal at the articulation point.

  • Patent number: 8383965
    Abstract: A top-pan balance having a pan, a weighing system, and an overload safety mechanism. The load cell (4) of the weighing system is connected to fixed points (1) on a housing of the weighing system by an upper connecting rod (2) and a lower connecting rod (3) as a parallel guide so as to be movable in the vertical direction. The pan is attached to a pan support (8/9) for securing against overload, the support being connected to the load cell through an auxiliary parallel guide (15/16) and through a biased spring element (17/18), whereby the pan is quasi rigidly coupled to the load cell in the permissible weighing range, but is only resiliently coupled to the load cell when the permissible weighing range is exceeded. At least one limit stop is fixed to the housing and limits the elastic deflection of the pan and the pan support in case of overload.

  • Patent number: 7732721
    Abstract: A precision force transducer having a spring element (1) whose load-dependent deflection is converted into an electrical signal by means of strain gauge elements (10). The spring element (1) is made of a precipitation-hardenable nickel-based alloy with a nickel content in the range of 36 to 60 percent and a chromium content in the range of 15 to 25 percent. The strain gauge elements (10) are composed of a polymer-free layered film system. This makes it possible to produce a precision force transducer that features great accuracy, low creep and low moisture sensitivity.
