Kistler expands its range of inspection systems for fastening technology with the new INSPECTOR torque wrench. This easy-to-handle device helps carry out process capability tests on bolted joints for evaluation and documentation of fastening processes under series production conditions in a matter of seconds. Coming with display/measuring unit, the new torque wrench also provides an interface with the CEUS and testXpert software applications for evaluation and archiving. Thanks to the further (or carry-on) tightening test method, a torque wrench is used to continue tightening the joint by a defined further rotation angle after it has already been fastened, and the resultant torque is then measured.
Simply carry-on tightening
Through recording and statistical evaluation of the fastening curve, suitable methods can be used to determine whether the bolted joint was produced in a controlled and capable process. Wilfried Blechmann, Head of the Fastening Technology Business Field at Kistler explained: "The new INSPECTOR electronic torque wrench from Kistler provides users with a high-performance tool for process capability tests. This is a compact, easy-to-operate tool that combines precise measurement technology with a very comfortable high-quality user interface. It will help users to assemble bolted joints reliably and provide proof of process capability in compliance with VDI/VDE 2645 Part 3."
