In aviation, the rail industry, and other industrial sectors, detecting surface and subsurface cracks, discontinuities, and other defects in components is critical to ensuring safety and reliability. Eddy current flaw detectors are designed specifically for reliably detecting and evaluating such defects, supporting safe and efficient inspections and quality control. These instruments allow for the complete inspection of component material at a relatively high throughput without damaging the tested material.
Positioned as the leading model within the eddy current instrument range, this flaw detector is designed for universal NDT applications, including confirmatory rail testing and manual inspection of aircraft and helicopter components.
Representing the newest generation of eddy current instruments, this portable flaw detector is designed for crack evaluation in rail, aerospace, energy, and industrial applications and is compatible with bolt hole scanners.
The eddy current machine is used for nondestructive testing of aircraft and helicopter wheels, providing 100 % automated inspection of wheel halves with simple, user-friendly controls and software.
The ready-to-use aviation eddy current inspection kit includes an Eddycon C or CL flaw detector, probes, a bolthole scanner, and calibration blocks. These tools allow the inspector to reliably detect surface and subsurface defects in aircraft components.
This compact flaw detector supports multiple eddy current channels and allows connection of up to 32 eddy current probes per channel. It enables scalable industrial NDT solutions and operates with stationary PCs, laptops, or tablets.
An in-service rail inspection system uses eddy current testing equipment to detect surface and subsurface rail defects. It can measure defect parameters at speeds of up to 24.9 mph (40 km/h).
Designed for continuous inspection of one rail of the track in a single pass, enabling eddy current testing of rails and switches, post-grinding control, selective track areas, and all major rail profiles.
Enables eddy current rail inspection with simultaneous testing of the left and right rails. Supports rail and switch inspection and post-grinding control of selective track areas.
Eddy current testing (ECT) equipment is used for various inspection tasks involving electrically conductive materials. Typical applications include the detection and identification of surface and subsurface cracks, material discontinuities, and other defects in various parts and holes, including cylindrical and complex-shaped ones. Eddy current flaw detectors are also applied to evaluate the electrical conductivity of non-magnetic materials and to measure paint and corrosion-protective coating thickness. This technology is additionally useful for inspecting weld quality by detecting surface-breaking and microcracks in welded joints. When operating under controlled inspection parameters, the equipment consistently delivers results suitable for routine industrial and maintenance NDT applications.
The operation of eddy current testing equipment is based on an electrical coil integrated into an eddy current probe that is energized by an alternating current from a flaw detector. This coil generates an electromagnetic field that induces eddy currents in the surface layer of an electrically conductive material. Defects, material properties, or geometry cause variations that disturb the current flow. These variations result in measurable changes in signal amplitude and phase. The flaw detector processes and displays these changes for defect detection and evaluation.
This operating principle provides high-accuracy, repeatable inspection results with minimal dependence on operator technique. It enables the reliable inspection of components with complex geometries and limited access where other NDT methods may be less effective. Signal response analysis supports the differentiation and characterization of defect types, thereby improving the reliability of defect evaluation. This method also ensures safe inspection conditions for operating personnel.
Selecting appropriate coil configurations and adjusting the test frequency optimizes inspection sensitivity and penetration depth for evaluating surface and subsurface flaws in flat, cylindrical, and complex-shaped components.
