  • Patent number: 9915558
    Abstract: Monolithic linkage structure having a base body and a load receiver guided in a Z direction relative to the base body by a plurality of parallel guide elements, wherein at least one parallel guide element is connected, via a first joint, on a first end to the base body and, via a second joint, on a second end distanced from the first end in an X direction to the load receiver, wherein the base body is configured on both sides of a plane, which extends in the Z direction and in an X direction, and wherein at least one parallel guide element has, on at least one outer surface facing away from the plane between the first joint and the second joint, at least one recess penetrating the at least one parallel guide element in the Z direction, through which projects a base body portion of the base body.

  • Patent number: 9188475
    Abstract: A precision weighing device is provided formed with a balance having a bridge element, which realizes a parallel guidance between a load receptor and base body by means of force-transmitting levers arranged in advantageously inside the bridge's structure. A balance is made insensitive to corner loads with a spaced-apart arrangement of two bridge elements having the features herein.

    Assignee: Wipotec Wiege- und Positioniersysteme GmbH
    Inventors: Jan Gottfriedsen, Tobias Stellwagen
  • Patent number: 9116032
    Abstract: The invention relates to a weighbridge for forming a scale, in which a load is distributed onto individual levers by means of two or more bridge elements, wherein oppositely rotating levers are coupled to one another in each bridge element in order to create a sum force in each individual bridge element. The sum forces from each bridge element are coupled via connection elements to superimpose them in order to form an overall measurement force detected by a force compensation system.

  • Patent number: 8853567
    Abstract: A weighing device, particularly an electromagnetic force compensating weighing device, with a weighing sensor unit connected in at least three mounting regions to a second unit such as a carrier unit or intermediate load plate. The second unit or the weighing sensor unit has connecting regions in at least two mounting regions, which employ a hinge structure that allows an essentially translatory shifting motion of the connecting region to avoid stress caused by temperature related expansion.
