Abstract
A load cell includes a first element, a second element and a sensor measuring force between the first and second elements along a first axis. In some embodiments, lateral and angular decoupling is provided by the provision of a convex surface between the first and second elements. The convex surface is slidable relative to at least one of the first and second elements in a first direction perpendicular to the first axis.
