TORQUE WRENCH WITH MEASUREMENTS INDEPENDENT OF HAND-HOLD POSITION

摘要

A torque measuring wrench includes a deflection beam provided with a socket head at one end and having a region of reduced cross-sectional area. Four strain gauges are mounted on the beam and connected in a measuring bridge, with one gauge disposed at the region of reduced cross-sectional area and the other gauges disposed closer to the ratchet head. A tubular handle is connected to the other end of the beam and encloses battery-powered control circuit including indicating means. The torque wrench measurements are independent of the position along the handle at which the force is applied by the user.
