Eddy-current flaw detector
The handheld instrument specifically designed for the detection of cracks and measurement of their depth, particularly effective at identifying stress-corrosive cracks within ferromagnetic metal constructions, even beneath layers of corrosion or protective coating.
This flaw detector facilitates the measurement of corrosive damage depth and protective coating thickness, combining magnetic and eddy-current methods for flaw detection. This unique feature allows users to inspect products with rough corroded surfaces and measure through varying thicknesses of insulating coating without requiring additional readjustment.
Application
- Pipes and pipelines
- Oil and gas pipelines
- Vessels and pressure vessels
- Energy production objects
- Structural details, machinery, and mechanisms
- Simultaneous identification and depth measurement of stress corrosion cracks and thickness of insulating coating, and/or corrosion.
- Continuous monitoring of insulating coating thickness to detect corrosion fissures.
- Real-time adjustment of readings.
- Adjustable threshold units for minimally detectable fracture depth and insulating coating thickness.
- Intuitive interface
Construction advantages
- Capability to use additional changeable sensors.
- Metallic housing of electronic unit for reliable performance in severe field conditions.
- Sensors with abrasion-resistant zirconium ceramics contact surface.
- Defect detection signalization through lighting and audio signals via loudspeakers or headphones.
The Eddy-current flaw detector ED-45 is engineered for use in both industrial and field conditions, requiring no additional adjustment for:
- Coarse and corroded surfaces (e.g., preowned pipes, structural parts, mechanisms);
- Damp and dirty surfaces;
- Surfaces with variable thicknesses of insulating coating.
