Magnetic Flux Leakage Testing (MFLT)
AC current flows through two rotating magnetizing yokes. The yokes magnetize the test piece at a distance of a few millimeters. Special test shoes with protected probes located between the yoke arms scan the surface of the test piece by sliding over it.

The AC magnetic field generates a magnetic flux inside the test piece. If the test piece has an inconsistency in its surface, the magnetic field is deviated and a leakage flux is generated. The sliding probes detect the leakage flux and the NOVAFLUX® testing system displays and reports this deviation including exact localization information.
Few advantages are :
  • Defects as small as 0.1 mm can be detected.
  • Highly sensitive test method for the detection of longitudinal defects on black steel bars.
  • No coupling liquid required.
  • Reliable and reproducable test results.

NOVAFLUX

PRÜFTECHNIK's latest product line is the flux leakage based NOVAFLUX inspection system. NOVAFLUX is used for the highly sensitive inspection of black and bright metal bars and seamless tubes. Longitudinal defects of a depth greater than 0.1 mm can be found. It handles high production speeds of up to 3 m/s and features a userfriendly touchscreen for easy operation. A detailed report of the test results permits further processing of defective, yet repairable bars, thus increasing the yield. NOVAFLUX is an attractive investment that will pay off quickly: It comes at a highly competitive price with three flux leakage sensor sizes to choose from. Alternatively, NOVAFLUX can be operated in combination with flux leakage sensor systems of other vendors.

As a renowned specialist of eddy current inspection systems for the semi-finished products industry with over 35 years of experience, PRÜFTECHNIK NDT provides the industry with a wide portfolio of testing equipment for reliable quality control. EDDYCHEK and NOVAFLUX test equipment is used in a wide variety of different production areas, for process monitoring and for the final inspection of tubes, bars and wire. Eddy current testing meets an extensive range of international standards including: ASTM, API, BS, JIS, ETTC, ENEL, DIN, SEP, etc.
