Abstract

A load cell body for measuring components of force and moment in plural direction includes an integral assembly having a rigid central hub and a rigid annular ring concentric with the central hub. At least three radial tubes extends radially along corresponding longitudinal axes from the central hub to the annular ring. Flexure members join the radial tubes to the annular ring. Each flexure member is compliant for displacement of each corresponding radial tube along the corresponding longitudinal axis. As a load cell, a strain sensor mounted on each radial tube measures strain therein.
