A low profile weigh scale includes a rectangular frame constructed on two opposite sides by U-shaped channel members. A plurality of removable platform members bridge central portions of the frame and are supported on their edges by angle irons on the sides of the channels. While the weigh scale has a relatively large weighing capacity, the frame and platform members can be easily disassembled and manually carried to different locations. In the preferred embodiment, load cells are mounted within the channel members at each corner. Removable covers are provided for the channel members to enable the user to gain easy access to the load cells for leveling purposes and the like.

Low profile weigh scale

A weigh scale includes a flexure beam disposed between a platform and the base. Load transmitting devices operate to deflect the beam as a function of the load placed on the platform. Overload protection is provided for the beam to restrict the amount of beam deflection to maintain it within its elastic limits to thereby prevent yielding of the beam.

Overload protection for a weigh scale having a flexure beam

A weigh scale apparatus in which forces caused by the applied load are transformed into moments of opposite sense and applied to opposite ends of a substantially rigid beam. Deflection of the beam is measured by centrally disposed strain gage resistors to produce an electrical signal quantity proportional to the applied load. The conversion of applied load to moments of opposite sense is accomplished by a pair of spaced parallel pivot members which are suspended by straps between the load receiving pan and the base such that the pivots tend to rotate in opposite directions. The beam is mechanically connected between the pivots such that it is subjected to the bending moment over substantially its entire length. A split scale device is provided by a composite pan, one portion of which is connected to the pivots directly and another portion of which is connected to the pivots through long lever arms to provide moment multiplication. A vibrator device for dithering the pivots is provided.
