Effectiveness meets highest precision
Precision is our strength, as the CIRCOFLUX sensor systems with rotating probes reliably detect small surface defects of 0.1 mm or greater. Due to the alternating field magnetization, an additional demagnetization is not necessary. The three available sensor systems cover a material diameter from 10 - 220 mm. This makes them suitable for a wide range of test tasks and ensure maximum effectiveness of AC flux leakage testing with throughput speeds of up to 4 m/s.
With the CIRCOFLUX evaluation electronic equipment by FOERSTER, you are guaranteed to achieve reproducible crack detection for hot rolled ferromagnetic steel bars thanks to the automatic adjustment processes. Integrated diagnostic functions ensure accurate automatic test results as well as high-precision testing of the surface of black materials for longitudinal defects. The unit is operated via an intuitive and modern touchscreen in the popular FOERSTER design.
