Abstract

A method and a device and system in which a torque applied to a bolt, screw or other fastener in a screw threaded joint using a pulse driven torque wrench is estimated. The pulse driven torque wrench is arranged with means for sensing torque applied by the pulse driven torque wrench, also with signal processing means and with control means to control the drive means. The present invention comprises memory and calculation means so that parameters may be calculated from measurements of torque applied. The applied torque is estimated from calculated parameters that describe the form of each pulse, enabling the applied torque to be accurately estimated. The main advantage of the invention is that it provides an accurate and consistent estimate of applied torque. It is also particularly fast and economic to use because no reset or re-calibration is needed for higher or lower torque values and for different fastener/joint combinations. The mode or rate of shut-off also may be pre-determined to suit the type of joint.
