Right-handed OrthogonalCoordinate SystemPrinciple of OperationAll Torque sensors manufactured by PCB are strain gage based measuring instrumentswhose output voltage is proportional to applied Torque . The output voltage produced bya resistance change in strain gages that are bonded to the Torque Sensor structure. Themagnitude of the resistance change is proportional to the deformation of the torquesensor and therefore the applied four-arm Wheatstone Bridge configuration shown in Figure 1depicts the strain gagegeometry used in the Torque Sensor structures.
