Abstract
A load cell comprising a load carrying structural framework is arranged with at least one measuring zone () arranged with a measuring means. A load F applied in the x-direction parallel to two outer beams () of the framework is transferred to two inner beams () by two side beams (). The load on the measuring zones () is greater than the load applied parallel to outer beams () in a ratio of the distance h between the joints of the two outer beams divided by the distance d between the joints of the two inner beams. When a load is applied in the y-direction parallel to the two side beams (), the load on the measuring zones is also greater than the load applied at the side beams, in this case by a ratio of the distance l between the joints (and), (and) divided by distance d. In a load cell according to the preferred embodiment of the invention measuring zones () are defined by recessesand planar gapsrunning from one side of the load cell to the other in the z-direction. The load cell according to the invention is accurate even with small loads and is insensitive to the effects of temperature gradients across the load cell in the x, y, or z-direction.
