Surface crack detection system THE ISOTEST 30 E mobile crack detection unit is a new, state-of-the-art power pack designed by Magnaflux GmbH of Essingen, Germany for magnetising specimens with AC or full-wave DC in magnetic powder testing. Satisfying a requirement expressed by numerous customers, this system complements the company’s range of Isotest mobile systems 60E (for test currents up to 6,000 A DC) and 100 E (for test currents up to 10,000 A DC) with a model designed for test currents up to 3,000 A DC and AC. The model 30 E features a new, wear-free electronic high-current change-over switch, which enables easy and quick switching between DC and AC with the simple push of a button, without the need for re- connecting or re-assembling high-current cables. This light-weight and extremely compact power pack provides exceptional mobility and flexibility on-site. Isotest 30 E is suitable for use in all industries where highest reliability under harsh conditions is a requirement, including the automotive and aeronautical industries, foundries, forging shops, steel production and processing, along with OEMs and suppliers, testing contractors and service providers. All three Isotest models enable the demagnetisation of work pieces previously magnetised with full-wave DC current by means of a multi-stage, low-frequency demagnetisation system. The control system is programmed in such a way that current control starts at least with the selected test current intensity and is then continued until zero current is reached. This ensures the complete demagnetisation of the work piece, as is required for many of the subsequent processing steps. Alternatively – depending on the type of magnetisation selected previously – demagnetisation with alternating current is also possible. To increase testing safety, the Isotest systems, which are designed for constant current magnetisation or impulse current magnetisation, feature a constant current control or (optional) current flow detection system. A broad spectrum of high-current cables, coils of various diameters and designs, and a variety of contacting options provides the user with maximum flexibility. Holger Wilhelm, head of sales office and service at Magnaflux, Germany, commented: “In the design of the new Isotest 30 E system, we were guided strictly by market requirements. We are offering a system that provides a maximum of operator convenience, safety and mobility, with a combination of features which is, to our knowledge, currently unsurpassed anywhere in the world. Our customers can now choose exactly the performance level that best suits their requirements. In addition to our three mobile standard crack detection systems, we also offer stationary systems for testing large work pieces, as well as customised designs – for example, we have built several systems with test currents up to 3x17,000 A for multidirectional testing.”
