The servo-drive delivers constant and reproducible movement (displacement) and therefore the force signal is recorded as a pure force/time curve. Recording the force signal at this rapid speed is possible thanks to the instrument's high sampling rate. The DIGIFORCE ® 9311 analyzes the force/time curve synchronously with the crimping process. The 8526 compression load cell is located in the lever and measures the pressing force. To monitor the crimping process, the force applied by the jaw segments to the material deformation is analysed as a force/time curve. Since safety-critical components are often involved, these production processes must be fully documented with 100% process monitoring.

It is essential to ensure strain relief between sleeve and cable and/or that the joints are both liquid-tight and gas-tight. In addition to 100% monitoring of the form-fit, the system must also identify a possible failure of one or more crimping jaw segments during the crimping process. Depending on the machine design, 4 to 16 jaw segments compress the components symmetrically to produce a form-fit.

Graphical evaluation elements used for monitoringĪ process that uses crimping and rolling machines to join (crimp) rotationally symmetric components and assemblies in a form-fit needs to be monitored.

High sampling rate ensures high-speed recording of force signal.
