Instrumented handle for use in lever, has strain gauges arranged in rosette and bonded to membrane placed in working plane on which stress is exerted, and lateral contraction unit concentrating strain due to exerted stress

摘要

The handle has three strain gauges arranged in rosette (4) at 120 degrees crossing a central point bonded to a center of a membrane (9). The membrane is placed in a working plane on which the stress is exerted and is perpendicular to an axial direction of the handle. A lateral contraction unit (8) concentrates the strain due to the stress exerted on an axis at the center of the membrane.
