External coil port

Cable-wrap magnetization for oversized parts

Every machine's power cabinet has an external coil port. When a part is too large or heavy to load into the machine, connect a flexible cable to the port and wrap it around the part to form a coil, so the part can be magnetized where it stands.

Cable-wrap magnetization: flexible cable wound in several turns around a large valve body on a pallet
Wrapped around the part
Cable-wrap magnetization: cable threaded through a bore in the end flange of the valve body

Indications under UV-A light

Fluorescent magnetic particle indications on parts and standard test pieces, photographed under UV-A light.

  • Magnetizing coils coated with fluorescent magnetic suspension, glowing green under UV-A light
  • Test piece on a flange face, its cross indication glowing under UV-A light
  • Test piece on the inner face of a large ring under UV-A light
  • Test piece on the outer face of a ring, with fluorescent particles gathered around it
  • A1 test piece held on a part, its circle and cross indications clearly visible under UV-A light
