Machine part strain measurement - is performed by strain gauges mounted on deformable element to magnify strain

摘要

A strain transducer is used for measurement of strain or deformation of machine parts or other components under load using strain gauges. It has a deformable element fixed to the moving part by rigid supports at separate mounting points, so that the neutral section of the element is perpendicular to the main strain direction, The device is designed to detect relatively smal forces despite relatively large distances fixing elements, and to enable easy compensation for cross forces. At least one strain gauge (4) mounted parallel to the machine part surface on the deformation element (6) with its measurement direction in a main load direction.
