Axial Column - 2 Gages In Opposite Arms


       

The physical configuration of the gages is the same as that used for the bending half bridge . But because the two active gages are now electrically connected in opposite arms of the Wheatstone bridge, this configuration cancels bending strains with equal magnitudes and opposite signs. The magnitude of the bridge output resulting from axial loads is relatively high (because of the additive effect) but is nonlinear (approximately 0.1% per each 1000 microstrain produced in the column by axial loads). And because any thermal output from the active gages is additive for this configuration, temperature compensation is the poorest of any configuration shown here.
