The invention relates to a load cell symmetrical about a central vertical axis and comprising first and second mounting surfaces, each on the same horizontal plane and configured for attachment to a support structure and to a loading fixture respectively.

A load cell has a monolithic measuring body. The monolithic measuring body has: a force-supporting section; a force-introduction section; and a linkage section disposed between the force-supporting section and the force-introduction section. The monolithic measuring body has a longitudinal axis between a force-supporting-side axial end and a force-introduction-side axial end. The longitudinal axis is configured to extend in a horizontal direction. The monolithic measuring body further has, in the force-supporting section, at least one mounting hole for attachment of the monolithic measuring body, the axis of the at least one mounting hole extending in the horizontal direction. At least one strain gauge is configured to sense tensile or compressive deformation of the monolithic measuring body and is in a region of the linkage section on a top side or a bottom side of the monolithic measuring body, the at least one strain gauge being oriented in the horizontal direction.

A cast load cell comprising a load sensing portion integrally cast with a first mounting portion. The load sensing portion has a flexure portion spaced apart from the first mounting portion by a flexure gap. The load sensing portion has at least one sensor cavity above at least a portion of the flexure gap. A second mounting portion is integrally cast with the load sensing portion above the flexure gap. A load sensor is connected to the load sensor portion and positioned within the sensor cavity above a portion of the flexure gap. The first mounting portion, the load sensing portion, and the second mounting portion define an integral, low-profile, weld-free, substantially homogenous unitary cast member.

A weighing scale and a load cell assembly therefor, the weighing scale including: (a) a weighing platform; (b) a base; and (c) a load cell arrangement including: (i) a load cell body, disposed below the platform and above the base, the body secured to the platform at a first position along a length of the body, and secured to the base at a second position along the length, the load cell body having a first cutout window transversely disposed through the body, the window adapted such that a downward force exerted on a top face of the weighing platform distorts the window to form a distorted window; and (ii) at least one strain-sensing gage, mounted on at least a first surface of the load cell body, the strain-sensing gage adapted to measure a strain in the first surface; and (d) an at least a one-dimensional flexure arrangement having at least a second cutout window transversely disposed through the body, the second cutout window shaped and positioned to at least partially absorb an impact delivered to a top surface of the load cell body.

A force transmission element for a balance or load cell is adapted to be arranged between a load receiving unit, receiving the load to be weighed, and a load application point of a load cell, in order to transmit the load force exerted by the load. The force transmission element is designed at least partly as a framework composed of hollow rods, in particular round rods, wherein the force transmission element, in particular the hollow rods, is/are produced at least partly using 3D printing technology.

The present disclosure relates to a weighing assembly (100) for a luggage case (101). The weighing assembly (100) includes at least one support (107) in contact with a surface that supports a portion of a weight of the luggage case (101). A floating element (108) is coupled to the support (107). A deflection member (110) is coupled to the floating element (108), and the portion of the weight of the luggage case (101) causes an elastic deflection of the deflection member (110). A load cell member (112) disposed adjacent to and separate from the deflection member (110). The load cell member (112) is separate from the deflection member (110) the elastic deflection of the deflection member (110) causes a deflection of the load cell member (112), the load cell member (112) senses the amount of deflection, which correlates to the portion of the weight of the luggage (101).
