Position sensing electronic torque wrench

摘要

The present invention provides a device for confirming that threaded fasteners have been tightened to the level of torque required by the assembly specification. An apparatus and method is provided for validating or verifying a fastener connection. A wrench or other torque tool can be engaged with a fastener to be tested. A rotation sensor is associated with the wrench for sensing rotation of the fastener and for generating a first output signal. A torque sensor is associated with the wrench for generating a second output signal corresponding to torque being generated by the wrench against the fastener. A processor is in communication with the rotation sensor to receive the first output signal and is in communication with the torque sensor to receive the second output signal. The processor analyzes the first and second output signals in accordance with a control program stored in memory.
