ABSTRACT:
A system for monitoring and/or controlling the torque applied by a fluid driven tool for driving threaded fasteners, such as tools driven by either air or oil. The system includes a fluid flow meter to measure a parameter which is a function of the rate of fluid flow into the tool during operation of the tool, a transducer for converting the measured parameter into an electrical signal, and a data processing unit for processing that electrical signal into a signal representative of the torque applied by said tool. A system for digitally processing the measured parameter and comparing it to predetermined expected parameters to infer the condition of the fluid driven tool and for reporting that inferred condition is also included. The system is applicable to both nutrunner type fluid tools and impact wrenches.
