testing & measuring

Detecting those faults In the wire and cable industry there are a number of demanding sensor applications which require the detection of joints and faults in order to automate additional process steps. Roland Electronic has developed a new eddy current- based system for these detection applications. Examples of such sensor applications are: detection of broken leads in extruded cables detection of cable connections after the extruder detection of the joint between a heating cable and a connecting cable detection of butt welds in wires detection of mechanical connections in continuously processed automotive gas tubes The third example in the above list is an especially demanding task because of the process speeds and the precision with which the connection between heating cable and connecting cable must be detected. • • • • •

For this purpose the cable is guided through the sensor orifice for printing and marking the joint with a black stripe. In a separate process step the cable is cut off precisely at the joint between heating cable and the connection cable.

The PC-based eddy current Weld Seam Detector SND 40 with the custom designed sensor STW functions very well for these applications. The system replaces an older analogue sensing system.

Covering all testing needs

TopScan AWM LC Due to the recent appearance of bundled cables in the EIA/TIA 568A standard, together with the 10GBASE-T specification, Aesa Cortailloid decided to launch a new measuring system – the Vega 1028 – to cover all testing requirements. The Vega 1028 is a high quality instrument with state-of-the-art measurement technology, which is fast, reliable and very accurate. It is delivered with a high end computer system. The tester can be equipped with a full range of software and hardware options to fulfil all possible requirements coming from customers. This tester has been especially developed to answer the rising demand of LAN cable manufacturers in testing cables according to the latest European and American Standards for Category 5, 5E, 6, 6A, 7 and 7A cables. This statement is valid for 4 pair cables but also for bundled cables up to 28 pairs. The latest standards for bundled cables require ‘Alien’ crosstalk parameters to be tested. These measurements are quite time consuming if they cannot be performed automatically, due to the high number of required test commutations as well as the terminations for the pairs not under test. The Vega 1028 tester fulfills the ‘Alien’ test requirements fully automatically. The switching technology, integrated by Aesa in its new Vega 1028 measuring system, which has proven its capabilities over the past years, brings an accurate, efficient and fast solution to the actual existing testing problems. Moreover, the flexibility of the latest generation software allows using the connecting frames in all possible configurations.
