IMPROVED FLEXURE SYSTEM FOR STRAIN-BASED INSTRUMENTS

摘要

A device for measuring forces on a sensor body, comprising a beam (110). An array (120) comprising at least one recess is formed in the beam. The array has a length-to-height ration of less than 1.0. At least one strain transducer (130) is mounted in at least one recess, wherein when incorporated in a sensor body the device is sufficiently rigid to provide low overall deflection while providing adequately high metric strain levels. Also given is a frame device with a clevis. Furthermore a deflectometer, dilatometer or diametric extensometer. Torque is measured with concentric rings and spokes bearing recesses.
