Air leak detector / electronic

LeakTEC is a powerful electronic tool for non-destructive leak detection of non-conductive single layer materials.

The LeakTEC measures a leak between a high-voltage electrode (DC) and counter electrode which can either be grounded or running opposed polarity. The LeakTEC ensures full process control and traceability.

It is typical in field applications to surface test moulded and welded joints in medical devices like medical tubes, containers, pipettes, cannulas and extruded film for medical bags etc.

This fully automatic test is capable of detecting pin holes even smaller than 3 microns by introducing an electrical potential between a detecting electrode and an electrical ground, (i.e. metal jig or mandrel holding the part) while the plastic part itself acts as the insulator.

In the event of detecting a crack or pin hole in the plastic material, an electrical contact is established between electrode and ground.

This pass/fail contact is processed via the integral generator module interfaced with the main machine control. The machine control can either enable a downstream ?part-reject? function or track trends in the manufacturing process, which can be fed back for early process adjustment or maintenance. Counter electrodes measurement is to ensure that all electrodes are fully working. Each counter electrode will then give out individual signal to be processed by the machine PLC unit.

To limit the high-voltage and minimize generation of static electricity Tantec offers its dual polarity system (patented).
