摘要： A digital indicating torque wrench comprising a shaft having a high modulus of elasticity and including a handle at one end, and an elongate actuating arm including a free end which moves with respect to the shaft in response to the application of torque to a workpiece. Displacement measuring means comprising an optical encoder measures the relative movement between the actuating arm and the shaft and provides deflection signals which are related to the amount of relative movement. A programmed microcomputer responsive to the deflection signals converts the amount of deflection into signals representing the amount of torque applied to the workpiece, and displays a visual representation of the applied torque.
