PLC and computer-controlled test benches for leak testing with client-specific operator-interfaces are the ideal solution for many tasks. This is particularly the case if: The wide variety of types of test pieces requires different procedures or sets of parameters A large number of different measurements such as pressure curves, times, mechanical and electrical values etc. are to be taken Process checks and documentation are required Example I Computer-controlled leak testing for commercial vehicle brake parts. All adjustment and testing procedures are fully automated. • Sealing Tests • Flow Tests • Pressure and time tests • Control unit settings • Functional tests Example II Threefold fully automated high pressure leak testing for ESP lines. Line lengths from 300mm-2,400mm. Measurement data visualised by Siemens OP 17 Control via Siemens S7 / 300. • Manual and automatic operation • Resolution of measurement 1 Pa • High pressure measurement technology for 200 bars • Marking of the tested “good” tubings • Forced ejection depending if passed or rejected Parts • Automatic acceptance of lines from production unit • Automatic operation of sealing instruments when line length changes • Lateral movement for removing from the production plant and passing to the test station Example III Tenfold semi-automatic high pressure leak tests for brake hoses, different lengths of lines and connecting pieces. • Automatic test piece adaption • Quick change system for different connection shapes • Forced ejection if parts rejected • High pressure generated 200 bar • Ergonomic layout of test piece mountings
