Transverse Sensitivity

Transverse sensitivity is the part of gage relative resistance change caused by strains perpendicular to the primary sensing axis of the grid. It is usually expressed as a percentage of axial sensitivity and measured in a uniaxial strain field (gages at 0° and 90°). When using strain gage rosettes, it is always wise to correct for transverse sensitivity, because by default at least one grid will see a high transverse strain when compared to the measured axial strain.
