This system is suitable for eddy current inspection of roller outer surface. The whole system consists of four parts: testing instrument, probe, machinery and electricity. Multi-frequency and multi-filter technology, impedance plane analysis and multi-amplitude phase-amplitude area alarm technology are used to realize automatic defect detection, automatic alarm and automatic sorting at the same time.
Applicable product specifications are: range: diameter 3-100mm,
Flaw detection standard: refer to GB/T 11260 Eddy Current Testing Method for Round Steel;
Standard Sample for Artificial Injury of Part Cracks
Defect depth: 0.05 mm defect length: 3 mm defect width: 0.05 mm
