Mechanical dynamometric tool e.g. wrench, for applying torque, has processing unit which permits to perform calculations on digital data that is obtained by electronic processing of signal

摘要

The tool has a mechanical balance break detection unit with a measurement unit (121) providing a signal corresponding to measurement of torque applied to a fixation unit. An amplifier (201), an analog/digital double conversion device (203) and a microcontroller (205) electronically process the signal. A processing unit (215) permits to perform calculations on digital data obtained by electronic processing of the signal. An independent claim is also included for a process of detecting a break of a mechanical balance.
