PRÜFTECHNIK's rotating systems are designed specifically to identify longitudinal, homogenous cracks and fissures found at the surface of the test piece. They are used for products that have a tendency to show longitudinal defects but do not have seam welds. Because the encircling coil is ideal for finding short transverse defects, it is often used in conjunction with the rotating system for a comprehensive testing strategy. PR??FTECHNIK offers a series of rotating systems (RS35HS, RS65, RS130) to cover a wide range of tube diameters. They are particularly easy to operate and maintain and are extremely robust to withstand the industrial environment. Precise test piece guidance and a lift-off compensation system ensure accurate test results. Eddy current inspection equipment suited for use with the rotating system includes the EDDYCHEK S and the EDDYCHEK 5, depending on the testing capabilities required.
Eddy current technology can be used to detect splices, connecting wedges or joint inside coated material such as steel tubes with PVC insulation. In this example, an EDDYSENSOR and an e
