Load cell with composite end beams having portions with different elastic modulus

摘要

A composite load cell utilizes end blocks mounted to the ends of a load cell body to increase the apparent bulk modulus of the end beams on the body. The increased modulus of the end beams improves cornering of the load cell, and further aids in the rejection of moment induced shears, including those due to off-center loading, thereby increasing the usable resolution of the load cell.
