DEFECTOARRAY sensor

With its newly developed segmented encircling coil, Institut Dr. Foerster GmbH & Co. KG offers cutting-edge sensor technology for significantly better materials testing. Designed in several segments, each with its own clearance coil, the patented DEFECTOARRAY sensor reliably detects defects, independent of whether the material is guided centrically or eccentrically.

Precise recording of defect positions
Highly sensitive multi-channel inspection enables very precise defect location on tubes or bars. The defect position is recorded not only in the longitudinal direction but also in the circumferential. Therefore, post-inspection, one can quickly locate the defects in the material – as well as draw valuable conclusions about the production process.

The Benefits

• Significantly higher reproducibility of test results due to innovative clearance compensation. This automatically leads to higher output of inspected material.
• Clearance compensation reduces negative influences brought by dimensional variations of test material and eccentricity.
• Exact defect locations, specified in both longitudinal as well as circumferential position.
• Reduced risk of mechanical damage to test material and/or sensor as the clearance compensation permits a bigger lift-off between material and coil.
• Higher sensitivity compared to conventional encircling coils enables reliable detection of the smallest defects on tubes and rods with larger diameters.
• Coil and nozzle changeover only necessary in 3 to 5 mm increments, depending on material diameter.
• Compatible with all existing mounts and magnetizing yokes from FOERSTER.
