About Fine wire

  • Inspection: Continuous inspection using encircling coil
  • Wire characteristics: Diameters down to 0.05 mm; tungsten, molybdenum, etc.
  • Production line: Drawing and rewinding lines
  • Inspection of fine wire using the eddy current method has become an industry standard for assuring quality products. Wire is inspected using encircling coils, available for diameters down to 0.05 mm. The eddy current inspection equipment keeps track of the location and threshold of any flaws and documents test results for future verification of wire quality.PRÜFTECHNIK offers a wide variety of eddy current inspection equipment that ranges from the most basic test equipment to powerful testers with wide-reaching capabilites for integration into central production control systems and 8-channel inspection using multiple coil systems.
