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 1200 RPM, it is designed for use in cold header operations, spring making, strut rod production and similar slow throughput operations.
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 120 VAC operation
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.
