DEFECTOTEST® Sensor systems H 2.859/2.860 Application The sensor systems H for the DEFECTOTEST® system are used for the non-destructive flaw testing of non-ferromagnetic semi-finished products. In conjunction with DEFECTOMAT® testers it is possible to test tube, bar and wire of round or profile cross-section in a continuous pass by the eddy-current method according to DIN 54 140. The sensor systems H cover the material diameter range from under 1 to approx. 100 mm. Fig. 1 Sensor systems H 90 and H 40

Method of operation The sensor system H is placed at a suitable point in the testing line so that the material to be tested passes through it centrally. There are several types of test coils which can be used in the sensor system. The most commonly used are round or saddle test coils in multi-difference connection. The difference connection causes adjacent areas of material to be compared. The difference coil will detect short, sharp surface flaws with great sensitivity. Its detection of extended flaws depends on the local variations in size. In addition to the difference windings all test...

Test coils The test coils are mounted either directly or by means of coil adapters in the test coil holder and located in the working position of the test coils is positively located by a slot at the side. The extremely robust construction is adequate for the demands of rough industrial use. The test coils are protected against mechanical damage by an elastic, hardwearing plastic coating. There is a socket for connecting the test coil directly to the electronic test equipment by means of a cable. The various diameters and adpaters are given in the ordering informations. Test coils and...

Protective guides The protective guides preferably used in the sensor systems H are made of plastic. Two guides are needed depending on the diameter (entry and exit). They protect the test coil against mechanical damage (e. g. bent material, variations in diameter or roughly sheared ends) and centralize and locate the test coil in the working position. It should be ensured that the nominal diameters of the protective nozzles and the test coils correspond. The complete protective nozzle set is available from 0.3 to 44 mm or from 1.2 to 100 mm for the sensor systems H40 and H90 respectively....
