Abstract:
1. A torque wrench, comprising: a main beam having a distal end and a proximal end; a drive element disposed at the distal end of the main beam; a handle assembly disposed at the proximal end of the main beam; a stationary beam having a distal end and a proximal end, wherein the stationary beam is fixedly secured to the main beam at a first location on the main beam and a first location on the stationary beam; a displacement sensor assembly that generates a signal indicative of an amount of displacement of the main beam relative to the stationary beam, the displacement sensor assembly including: an electronic component configured to generate a torque measurement based on the generated electrical signal, and to store at least one of the generated electrical signal and the torque measurement for a plurality of positions of the main beam relative to the stationary beam.
