A method for processing torque transducer data is provided. The method includes sampling a signal received from a torque transducer (14). The cycle count stored on a data memory device (112) at the torque transducer (14) is then incremented if the sampled signal indicates that a torque cycle has occurred.

System and method for monitoring tool cycles

A circuit (31) for use with a torque transducer (32) is provided. The torque transducer (32) generates a signal in response to an applied torque. A data processor (100) connected to the torque transducer (32) receives the signal. The data processor (100) and the torque transducer (32) are both contained within a torque transducer housing (15).

System and apparatus for a torque transducer with data processing

A method and apparatus for recovering torque lost due to joint relaxation in threaded fastener assemblies or joints. The present invention is especially adapted for use with medium-to-short or gasketed joints. In the practice of an exemplary embodiment of the invention, the torque of an electric nutrunner is pulsed at the end of a fastener tightening cycle between programmed maximum and minimum torque values which have been selected to overcome the static to dynamic torque ratio of the joint while maintaining the motor and gearing of the nutrunner in a loaded condition to ensure maximum nutrunner durability.
