Abstract
A force moment sensor for interjection in a load path comprises two rings having a common central axis joined by a resilient wall. Three or four tongue-like targets attached to one of the rings and equally spaced about the periphery of the ring project parallel to the central axis and a like number of proximity sensing assemblies attached to the other ring detect the proximity of these targets. These target-sensing assembly pairs allow sensing of forces along the central axis and torques about the two shear axes. Three or four additional tongue-like targets attached to one of the rings and equally spaced about the periphery of the ring project perpendicular to the central axis and a like number of sensing assemblies attached to the other ring detect the proximity of these targets. These target-sensing assembly pairs permit the measuring of forces along the two shear axes and torque about the central axis.
