ROTOFLUX® AC

Flux Leakage Tester for Detecting Defects in Hot Rolled Black Steel Bar

  • Designed to test hot rolled bar from 10mm to 180mm in diameter.AC Flux leakage in NDT
  • Incorporates the latest multiplexing and wireless signal transfer features to minimize noise while maximizing sensitivity.
  • Detects longitudinal flaws as small as 0.1mm deep on hot rolled bars and rods.
  • Operates up to 900 rpm, depending on product diameter.
  • A simple adjustment tool allows for quick resetting for dimensional changes.
  • Operates with Rotoflux® AC electronics.

Until recently, MAC® had been testing hot rolled bar with Eddy Current rotaries, which find defects down to 0.2mm deep. Now, new Rotoflux® AC technology extends this capability to finding even smaller defects and to products with surface conditions that often make finding shallow defects very difficult, if not impossible.

AC FLUX LEAKAGE TECHNOLOGY IN NDT

Highly sensitive AC technology is especially well suited to test hot rolled black steel bars and rods that have surface conditions which used to make finding shallow defects very difficult, if not impossible.NDT in AC Flux Leakage

  • AC technology uses two encircling magnetization yokes and alternating current flows.
  • Without contact, these yokes magnetize the test material in the transverse direction.
  • The magnetic flux is concentrated on the material’s surface and is particularly sensitive to minor surface defects since the operating probe examines a very small portion of the entire surface at any one moment.
  • MAC’s® Rotoflux® AC Flux Leakage Tester was designed for use with materials such as hot rolled black bar and can find defects as small as 0.1mm deep.
