MAC INTRODUCES NEW

ROTOMAC® 25RM EDDY CURRENT ROTARY

Cost-Effective Eddy Current Rotary for Testing Wire & Rod

The Rotomac®25 RM is the latest in MAC’s line of eddy current rotaries.  Packaged with our Minimac® 60/65 single channel eddy current electronics, it provides cost effective, reliable on-line inspection for longitudinal surface defects in wire, rod and heavy wall tube, 3 to 25mm diameter. 

Operating at 1000 RPM, it is designed for use in cold header operations, spring making, strut rod production and similar slow throughput operations.

Other features:

  • Throughput speeds up to 12 meters per minute

  • Out-of-round product can be inspected using our highly accurate distance compensation with absolute test probes

  • Standard single phase AC power input

  • Bushings keep product centered for a more accurate test

  • New air ride probe arm design, with convenient, easy access probe adjustment

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.
