Abstract
A strain gauge assembly includes: a strain gauge comprising a plurality of resistive elements connected as a Wheatstone bridge or half Wheatstone bridge; an excitation signal generator arranged to provide an excitation signal to two resistive elements of the strain gauge; phase shifting circuitry arranged to determine phase shifts in the excitation signal responsive to changes in resistance of the two resistive elements and an end stage configured to output a measure indicative of the phase shift as an indication of strain on the assembly.
