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.
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."
