Eddy Current Array Products

Eddy current array (ECA) technology provides the ability to electronically drive and read several eddy current sensors positioned side by side in the same probe assembly. Data acquisition is made possible through the use of multiplexing, which avoids mutual inductance between individual coils.

Eddy Current Array Instruments


Performs eddy current array testing inspections. The test configuration supports 32 sensor coils (up to 64 with an external multiplexer) working in bridge or transmit-receive mode. The operating frequency ranges from 20 Hz to 6 MHz with the option of using multiple frequencies in the same acquisition.

Eddy Current Array Probes and Solutions

Doubler Edge Skin Crack Inspection Solution

The Doubler Edge Skin Crack Inspection solution utilizes the latest ECA technologies for subsurface detection. The C-scan allows for higher probability of detection and better reproducibility. This solution is a major step forward in terms of reduced inspection time.

Stress Corrosion Cracking SolutionsNEW

Olympus offers a range of productive solutions to detect or evaluate the depth of surface-breaking stress corrosion cracking. These solutions are based on the OmniScan MX ECA, a powerful and easy to use eddy current array flaw detector.

ECA Subsurface Crack Detection

The Subsurface Crack ECA inspection solution is capable of scanning through the first aircraft layer (skin) to detect cracking present on the 2nd layer, without the need for paint removal. This solution is available in two ECA probe versions (commercial and military aircrafts), both covering at least 64 mm in a single pass.

ECA Subsurface Corrosion Detection

The Subsurface Corrosion ECA inspection solution performs rapid inspection of large areas for potential corrosion. Available in two probe versions (commercial and military aircrafts), this solution can evaluate the severity of hidden corrosion (defect depth) in an instant, without the need for paint removal.

ECA Surface Crack Detection

The Surface Crack ECA solution proposes an ergonomically-improved version of the SBBR-026 high-resolution ECA probe. This solution detects surface-breaking cracks at a very productive rate, even through paint and thin coatings. This is particularly well-suited for performing fast inspections of aircraft fastener rows.
