Overview
The MAIERIC Array Eddy Current Testing Instrument is a high-performance, portable non-destructive testing (NDT) system engineered for rapid, high-resolution surface and near-surface flaw detection in conductive materials. Based on the principle of electromagnetic induction, the instrument generates alternating magnetic fields via an array of precisely spaced, independently driven eddy current probes. When these fields interact with a conductive test piece, induced eddy currents are perturbed by material discontinuities—such as fatigue cracks, pitting, corrosion, or subsurface voids—producing measurable impedance changes in the sensor coils. Unlike conventional single-probe eddy current systems, the array architecture enables simultaneous multi-point excitation and acquisition across a defined inspection zone, eliminating mechanical raster scanning and significantly increasing inspection throughput without compromising spatial resolution.
Key Features
- Multi-frequency eddy current capability: Supports simultaneous operation at up to four independent frequencies per channel, enabling depth discrimination, lift-off compensation, and enhanced signal-to-noise ratio in complex geometries or coated substrates.
- Modular array probe design: Configurable probe layouts—including linear, rectangular, and curved arrays—are optimized for specific part geometries (e.g., turbine blades, fuselage skins, heat exchanger tubesheets) and can be tailored to application-specific coverage requirements.
- Portable, battery-powered architecture: Integrated ruggedized enclosure with IP54-rated ingress protection, ergonomic handle, and onboard 7-inch capacitive touchscreen display for real-time data visualization and field operation without external computing hardware.
- Real-time C-scan imaging: Onboard FPGA-accelerated signal processing delivers full matrix capture (FMC) and synthetic aperture focusing technique (SAFT)-enhanced imaging with sub-millimeter lateral resolution and depth-encoded color mapping.
- Automated inspection workflow: Programmable scan paths, trigger-based data acquisition, and integrated encoder synchronization support repeatable, operator-independent inspections compliant with ASME BPVC Section V and ASTM E309 standards.
Sample Compatibility & Compliance
The instrument is validated for use on non-ferromagnetic and ferromagnetic alloys including aluminum, titanium, stainless steel, and Inconel. Probe selection and frequency tuning are calibrated per material conductivity (1–60% IACS) and permeability. System compliance includes adherence to ISO 12718:2018 (Eddy Current Testing — Vocabulary), EN 13588:2016 (Non-destructive testing — Qualification of NDT personnel), and supports documentation traceability required under AS9100 Rev D and FAA AC 150/5370-10C. All firmware and calibration records maintain audit-ready revision control aligned with GLP/GMP principles.
Software & Data Management
The embedded MAIERIC ECT Suite v4.x provides intuitive configuration of array parameters, real-time A-scan/B-scan/C-scan overlay, and defect sizing algorithms per ASTM E215 and E1004. Raw impedance data is stored in standardized HDF5 format with embedded metadata (probe ID, frequency set, position timestamp, environmental temperature). Export options include ASCII, CSV, and DICOM-RT for integration into enterprise NDT data management platforms. The software supports 21 CFR Part 11-compliant user authentication, electronic signatures, and immutable audit trails for regulated aerospace and nuclear applications.
Applications
- Aerospace: Rapid screening of aircraft skin lap joints, wing spar webs, and engine compressor disks for fatigue-induced microcracks.
- Power generation: In-service inspection of steam generator tubing, turbine blade roots, and weld overlays in nuclear and fossil-fuel plants.
- Rail transport: High-speed rail axle and wheelset inspection for subsurface transverse defects prior to service deployment.
- Automotive: Quality assurance of aluminum castings, welded battery enclosures, and EV motor stator laminations.
- Manufacturing: In-line verification of additive-manufactured metal parts for porosity, lack-of-fusion, and surface-breaking flaws.
FAQ
What types of materials can be inspected with this array eddy current system?
Conductive metallic materials including aluminum, copper, titanium, austenitic stainless steels, and nickel-based superalloys. Ferromagnetic steels require specialized low-frequency configurations and permeability compensation.
Is the system certified for use in regulated industries such as aerospace or nuclear?
Yes—the hardware and software architecture supports compliance with AS9100, EN 9100, and NRC regulatory guidance for NDT equipment qualification. Calibration certificates and IQ/OQ documentation packages are available upon request.
Can the array probe be customized for irregular or curved surfaces?
Yes—MAIERIC offers custom probe housing designs with conformal coil arrays, flexible printed circuit substrates, and spring-loaded contact mechanisms for consistent coupling on radiused or contoured components.
Does the instrument support automated reporting and integration with plant-level CMMS or SAP systems?
Standard export modules enable structured XML and JSON output compatible with common maintenance management platforms. API access for direct database ingestion is available under OEM licensing agreements.
