Shear Rosette Strain Gauges HA Series
Shear strain gauges are designed to measure shear strain resulting from torque or torsional loading. They can feature either one or two measuring grids attached to a single carrier. In a single-grid configuration, the strain gauge element is oriented at a 45° angle relative to the shaft axis. A two-grid shear strain gauge, also known as a V Rosette, has measuring elements set at 45° and 135°. These gauges are commonly used in applications such as engine shafts and drivetrains, where they can be used to calculate shaft power based on strain measurements.]
