Pulsed Eddy Current
PEC utilizes a non-contact electromagnetic method to inspect insulated pipes and vessels for wall loss. A hand held probe generates a magnetic field which creates eddy currents in the test material. The probe monitors the decay of the eddy current field to determine changes in wall thickness. Thicker materials decay slower than thinner materials. Results can be given in a percent wall loss.
Benefits of Utilizing Pulse Eddy Current:
- Detects surface and near surface defects.
- Test probe does not need to contact the part.
- Method can be used for more than flaw detection.
- Minimum part preparation is required.
While current methods for measuring wall thickness over insulation (liftoff) without removing it all have severe limitations, ACTT utilizes Lyft, a high-performance solution reinventing PEC. The patent-pending Eddyfi® solution features:
• State-of-the-art portable instrument
• Standard pulsed eddy current array (PECA) technology
• Real-time C-scan imaging
• Fast data acquisition
• Grid and dynamic scanning modes
Lyft can scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. It also benefits from a range of PECA, single-element PEC, and application- specific probes to support various applications
