MINIMAC® II SINGLE- OR 2-CHANNEL DIGITAL TESTER
Minimac® II lets you take advantage of eddy current technology’s versatile capabilities to deliver high-performance testing for tube, bar, wire and parts. With an embedded host computer, this fully digital instrument provides up to two test channels of Flaw, Absolute or any combination, at an economical cost.
- Detect short surface and some subsurface defects, including laps, slivers and cracks in tube, bar, wire and parts.
- Inspect for long, continuous defects.
- Find weld line faults including short ID or OD defects.
- Test magnetic and non-magnetic grades.
- Use up to two test channels of flaw, absolute or any combination.
- Operate at speeds up to 4000 f.p.m. with standard test coils. Operate at higher speeds with wide-spaced coils.
- Operate with one or two test channels for encircling coil applications.
- Use two channels for rotary spinning probe systems.
- Supplied as a one channel instrument with an optional second channel.
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:
- 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.
