MULTIMAC® – MULTICHANNEL EC

MultiMac-silh-web

Eddy Current Instrument for Testing Tube, Bar, & Wire

  • Operates with encircling, sector, or rotary test sensors.
  • Up to eight test channels, null or absolute, can be used in any combination.
  • Detect short surface and some subsurface defects in tube, bar, and wire.
  • Inspect welded tube for short ID or OD defects in the weld zone.
  • Find seams and long, continuous flaws using a rotary test probe.
  • Test magnetic or non-magnetic material.
  • Offers broad test frequency selection from 1KHz to 5MHz.

The versatile MultiMac® lets you configure your eddy current test applications the way you want—all with one tester. Test channels can be individually configured for two ECT coil technologies, eliminating the need to invest in multiple testing instruments. MultiMac® is also available in other cabinet configurations.

EDDY CURRENT TECHNOLOGY IN NDT

MAC’s® Eddy Current Testing (ECT) systems incorporate computer-based test instruments and test coils that use two ECT coil technologies: encircling and sector coils, and spinning or rotary probe coils.

  • Encircling and sector Eddy Current coil tests perform in this manner.Eddy Current Technology in Non Destructive Testing
  • The product is passed through or adjacent to an electrical test coil, which
    has been excited by an alternating current.
  • This induces a flow of eddy currents around the test material or in the
    case of a sector coil, in the area under the coil.
  • Short, intermittent anomalies or flaws cause a variation in the eddy
    current pattern, which the instrument detects.
