Instruments and Systems
 Semi-finished products, such as wires,bars and tubes, are tested for local flaws in the form of cracks and holes by encircling through-type coils. The surface of semi-finished products or components is scanned with scanning probes. This allows maximum flaw resolution.
Example application: Two scanning probes scan defined surface zones of a rotating brake disk.

Automatic tester for flaw testing on disks and valve spring plates Statograph Sensor systems For surface flaw testing on components, so-called scanning probes are used as sensors. The user has a wide variety of models, adapted to all imaginable specimen geometries. The part surface to be tested is examined by one or more eddy current probes.In general, the test specimen is put into rotation through a suitable handling mechanism and scanned with a probe which is fixed or moves linerally. As an alternative to this, a rotating probe which tests the part in a fixed position can be used. Because of the importance of the sensor system, attention is placed on precise manufacturing and continuous further development of test probes.

There are various configuration levels, ranging from the single-channel, low-cost compact instrument through to the multi-channel system in which a Defectomat channel may also be integrated. Rotating Test Heads for use on round stock cover the diameter range from 2 to 130 mm. The most used are the Ro20, Ro35, and Ro 65. Typical fields of application include wire drawing machines, copper tube winders or finishing sections in the bright steel sector. Eddy-current testing with rotating sensors guaranteeing maximum detection sensitivity for surface-exposed, longitudinally oriented flaws on bright material. Individual arrays with rotating disks scan flat and profile material, e.g. when testing rails and shotblasted rectangular billets.

Metal Detectors Metal detection using the eddy current principle which generates with one or two frequencies an electromagnetic field. This field is used for the detection of hidden metal objects, even objects with very low metal content. All metals can be detected. Object detection with ec ( eddy current) method: The active detection sensor of the ec-technology is generating an electromagnetic field. This causes eddy currents in the object to be detected. These eddy currents generate a secondary electromagnetic field which is detected and evaluated by the receiver sensor.

Detection of ferromagnetic UXO (unexploded ordnance) Detection, localisation and mapping of unexploded ammunition, explosives and chemical pollutants in ferro-magnetic containers or with ferro-magnetic constituents. These detectors number amongst the most modern hand-held detectors for underground, underwater and in-borehole detection and for vehicle- aided detection. - Fast assembly, easy handling and operation
- Maintenance-free sensor tensioning strap technology, adjusted for life
- High detection sensitivity owing to the performance-enhancing, larger base clearances of the differential magnetometer

The range extends from the simple Ferex LCD instrument with liquid- crystal display, through the classic pointer instru- ment Ferex API to the Datalogger versions Ferex DLG, Ferex DLG with GPS Navigator and Ferex DLG GPS Cartograph. Thus, the Ferex 4.032 can be adapted individually to the customer's needs for performing the particular detection tasks. Together with the Ferex Dataline 4.800 evaluation software, this allows detection, localisation, identification and mapping on the Datalogger versions.

Magnetic Flux Leakage Systems
The leakage-flux probe method is used for ferrous, hot-rolled surfaces with round cross-sections. On the Circoflux, the alternating field method is used for highly sensitive detection of longitudinal surface flaws, primarily on hot-rolled bar stock. On the Rotomat / Transomat, the DC field method is used for detection of external and internal flaws on hot-rolled tubes. Either longitudinal flaws or transverse flaws are detected, depending on the magnetisation direction. API and ISO standards describe the method.
Circoflux - Photo 1, Photo 2, Photo 3 The Circoflux is particularly suitable for detecting longitudinally oriented surface flaws on hot-rolled, round bar steel owing to its very special high-energy alternating-field leakage-flux principle. A flaw resolution upwards of 0.1 mm flaw depth is conventional. 3 rotating heads are available for the diameter range 10 - 180 mm. Special solutions with stationary test heads and rotating material are imple- mented for larger dimensions. Rotating Test Heads for the Circoflux
Ro 20, 35, 65, 75,100,180
Rotomat / Transomat The DC field leakage-flux method is suitable for detection of flaws on the inside and outside surface for testing hot-rolled, seam- less steel tube in the diameter range 20 - 310 mm. Either the Rotomat or the Transomat is used, depending on the flaw orientation (longitudinal or transverse). Generally, both systems are combined, in some cases supplemented by wall thickness measurement and a material mix test in so-called multi-test units.
Magnetic Sorting Bridges The testing instruments of the Magnatest family offer you the entire range from low-cost instruments for the simple Yes/No sorting through to high end instruments with multidimensional regression analysis. Common to all of them are their high quality test results and the possibility to examine specific magnetic characteristics of the material through the analysis of the harmonic wave spectrum.
Magnatest D 3.623 - Photo
The newest member of the Magnatest family. Fully digital test electronics from the signal excitation through to evaluation. Compact, attractive and economical, this new device joins the existing product range for non-destructive magneto-inductive testing. Like the others in the series, the Magnatest D offers the possibility to perform uni-frequency as well as sequential multi-frequency testing. Furthermore - and this is new - it also masters simultaneous multi-frequency testing (impulse technique), so that both the quality of the test results and the throughput are raised substantially at the same time.
Magnatest S 3.625 - Photo The reference instrument in the field of magneto- inductive testing. Unequalled with respect to test sensitivity and evaluation possibilities. Multi-frequency excitation combined with harmonic wave evaluation and multi-parameter analysis to suppress interference.

Applications The measurement transducers (test coils and scanning sensors) are just as important as the use of a high performance test instrument. A measurement transducer adapted optimally to the purpose of the test and the test object is a necessity for the successful solution of every testing problem. A wide range of standard transducers (coils and scanning sensors) as well as the possibility to manufacture special transducers makes it possible for us to react flexibly to the widest range of problems.
