Abstract
A transducer body having a traditional single-axis envelope capable of multi-axis measurements. The transducer body includes coaxial base ends with an intermediate flexure element in the form of a ring having an internally centered stiffening web which reduces deflection and localizes strain for accurate high-capacity single-axis load measurements, as well as for bending and shear. The invention further includes a novel arrangement of strain gages on the transducer body, preferably including three sets: strain gages on the stiffening web to measure single-axis loading along the longitudinal axis of the transducer body; bending measurement strain gages spaced at 45.degree. around the periphery of the ring element; and shear measurement strain gages located at 90.degree. locations on the periphery of the ring.
