Biaxial Load Cell with Highly Anisotropic Force Resolution

Technology description

This novel load cell utilizes beam theory and geometry to concentrate stress for the biaxial measurement of anisotropic forces. The load cell is made from precisely machined metals with highly engineered features to concentrate stress. Wheatstone bridges accurately measure and decompose loads in two directions (along the y and z axes). The load cell's unique geometry allows force resolutions that are 1000 times greater in the z-direction compared to the y-direction.

The ranges of loads detected in each direction enable the effective measurement of friction coefficient or anisotropy index from 3 x 10 -6 to 250.
