Heating tube

Joints that link individual tubes for sheathing can easily be identified using an eddy current probe.
Rubber-coated rail Rubber-coated rail

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 CATV cabling

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

PRUFTECHNIK 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 in the metal within. When it detects a discontinuity, the EDDYSENSOR transmits a delayed or undelayed signal to a saw or paint marker which can then cut or mark the piece at the correct place.
