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.

A load cell comprising:
- A first element;
- A second element;
- A coupling between the first and second elements, the coupling including a convex surface slidable relative to at least one of the first and second elements in a first direction perpendicular to a first axis;
- and
- A sensor measuring force between the first element and second element along the first axis.
A load cell comprising:
- A first element;
- A second element;
- A coupling between the first and second elements, the coupling providing angular decoupling of the first and second elements and decoupling of the first and second elements in a lateral direction perpendicular to a first axis;
- and
- A sensor measuring force between the first element and second element along the first axis.
A load cell comprising:
- A first element;
- A second element;
- A sensor measuring force between the first element and second element along the first axis;
- and
- A trap element slidable in a first direction perpendicular to the first axis relative to at least one of the first and second elements, the trap element limiting the travel of the first element toward the second element along the first axis.
A load cell comprising:
- A first element;
- A second element;
- A sensor measuring force between the first element and second element along the first axis;
- the first and second elements being biased toward one another to create a preload on the sensor.
A load cell comprising:
- A first element;
- A second element wherein one of the first and second elements at least partially surrounds the other of the first and second elements;
- A sensor measuring force between the first element and second element along the first axis;
- and
- A bushing disposed in an annular space between the first and second elements.
