Benefits of the eddy current array (ECA) Doubler Edge Skin Crack Inspection solution
- Time saving: up to ten times faster
(typically 10 hours/person for 737 inspections).
- Referenced in the Boeing 737 manual
(NTM 737 NDT 53-30-25 Part 6).
- Replaces existing ECT procedures
(NTM 737 NDT 53-30-18 Part 6).
- Identical defect sensitivity to ECT.
- Higher probability of detection.
- Better reproducibility.
- Intuitive imagery with the encoded C-scan view.
- No need for paint removal.
The doubler and rivets appear on-screen for optimal probe positioning. The green/red color palette offers easy data interpretation.
Probe Specification
- 32-channel probe.
- Frequency range: 4 kHz to 225 kHz.
- Probe coverage: 64 mm.
- Cable length: 2.4 m.
- The encoder and probe cable are bundled together.
- Includes a special encoder holder.
Probe Performance
- Not sensitive to the corner of the doubler.
- Optimized to detect typical subsurface cracks in aluminum sheets with thicknesses up to 1.2 mm.
- Detects cracks up to 50% deep and 12 mm long on the far side.
Display showing C-scan, impedance plane, and strip chart views. Note that the doubler edge and rivets are clearly visible.
Excellent replacement for magneto-optic imaging (MOI) inspection systems
- Less expensive.
- Easier to use.
- Up-to-date technology based on proven eddy current technique.
- Data-recording capabilities.
