Abstract
A torque wrench for use in driving fasteners is provided. The wrench includes an electronics unit disposed within a body of the wrench that is capable of sensing and measuring the torque applied to a fastener by the wrench and providing an output of the level of torque to the user. The electronics unit is also disposed within a barrier in the body that isolates the unit from the exterior environment around the wrench. The data sensed by the electronics unit can be utilized to provide feedback to the user regarding the operation of the wrench, and to monitor the overall operation of the wrench for calibration purposes, among other functions. During use, the wrench can provide the user with visual, audible and tactile feedback regarding the operation of the device relative to stored maximum torque values stored in the electronics unit.
