Abstract

A load cell of the shear-link type comprising a solid body of high modulus of elasticity material having a longitudinal axis of sensitivity and longitudinally spaced transverse slots entering the body from opposite directions to define the shear link. The body is bored out in the area of the shear link to create a stress concentration which is monitored using bonded-on strain gage resistors connected in a Wheatstone bridge circuit.
