Strain on the surface of the axis is proportional to the torque applied to the axis. We also supply gauges in many other configurations, as well as gauges with specific creep characteristics and full bridge gauges for use in transducers. Therefore, strain gauges used in a shear strain configuration can be used to determine vertical loads (F); this is more commonly referred to as a shear beam load cell. Full-Bridge Strain Gage. The calculated Strain values can then be used to determine the stress state at each sensor location for the given load. Home document.write('
