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 encircling coil are used.
Joints that link individual tubes under sheathing can easily be identified using an eddy current probe.
Continuous rails are more lightly constructed in places where they will later be sawn apart. Sheath optically hides these positions but they are easily and automatically identified using the eddy current test method.
CATV cabling has radiation openings located in strategic places. Eddy current testing can identify these openings even though they are hidden beneath the extruded PVC sheath.
Eddy current sensing equipment
PRÜFTECHNIK offers a very basic eddy current tester, the EDDYSENSOR, that is ideal for precisely these sorts of simple sensing tasks. Whereas light barriers or other standard sensors are not effective, eddy current signals penetrate the sheath and detect discontinuities or splices in the metal within. When it detects a discontinuity, the EDDYSENSOR transmits a delayed or undelayed signal to a saw or color marker which can then cut or mark the piece at the correct place.
