Abstract
A helical load cell includes a first pair of transducers disposed along a neutral axis of a helical coil. A second pair of transducers is disposed in diametrically opposed relation to the first pair. Sensitivity to side loading is eliminated by 'splitting' the second pair of transducers. In another embodiment, each of the transducers in each pair are respectively oriented parallel and perpendicular to a neutral axis of the coil. This configuration provides a measure of torsional forces.
