Abstract
A high-capacity low-profile load cell for measuring compression force. The load cell comprises a support ring, a diaphragm supported by the support ring, and first and second pluralities of strain gages arranged under the diaphragm for detecting strain produced by application of a load from above. The diaphragm comprises a slug portion and a plate portion that surrounds and supports the slug portion. The slug portion has a height greater than a thickness of the plate portion. The first plurality of strain gages is disposed on a bottom surface of the slug portion, while the second plurality of strain gages is disposed on a bottom surface of the plate portion. These strain gages are electrically connected to form a Wheatstone bridge.
