The OmniScan MX
A Field-Proven, Dependable Instrument
With thousands of units being used throughout the world, the OmniScan® MX is a field-proven, reliable instrument that is built to withstand harsh and demanding inspection conditions. Compact and lightweight, its two Li-ion batteries provide up to 6 hours of manual or semi-automated inspection time.
The highly legible 8.4 in. (213 mm) real-time color display of the OmniScan MX enables you to see defects and details under any light conditions. Navigate your way through the instrument’s simple and intuitive interface using the scroll knob and function keys, or by connecting a USB mouse to facilitate the inspection analysis.
One Platform, Two Modules, Three Technologies: More Flexibility
To meet the requirements of a broader range of applications, eddy current testing (ECT), eddy current array (ECA) and the new bond testing (BT) C-scan technology are available in two module versions. Both of these modules are compatible with the MXE (ECT/ECA) and MXB (BT C-scan) software, providing easy transition between technologies and a very short learning curve.
ECA is just like ECT
Large Coverage, Fast Scanning, and Higher Probability of Detection
Eddy current array (ECA) technology incorporates several traditional bridge or reflection (driver-pickup) probe coils in order to achieve a much larger coverage in a single inspection pass. Additionally, each ECA probe model is carefully designed to maintain a high probability of detection of a targeted defect range, all along the probe length. With the OmniScan® MX ECA, you can use ECA probes at fast manual-inspection speeds, offering a powerful and productive inspection with color representation and archiving capability.
Inspection through Thin Coatings
Eddy current testing (ECT) technology works on the principle of magnetic coupling of a probe sensor (coil) close to a test specimen (conductive material, ferromagnetic or non-ferromagnetic), generating eddy currents inside the test specimen, and displaying signals on the instrument’s impedance plane. With eddy current technology, you can detect defects through thin coatings (such as paint), as long as the distance from the probe to the metal is kept reasonably low—typically in the order of 0.5 mm to 2.0 mm.
As eddy current array and ECT technology share the same basic principles (and physics), it can also perform inspections through paint while offering all advantages of ECA, including large coverage, fast scanning, high probability of detection and color imaging.
Inspection through Thin Coatings
Probes used to perform eddy current inspections are made with a copper wire wound to form a coil. The coil shape can vary to better suit specific applications.
The alternating current flowing through the coil at a chosen frequency generates a magnetic field around the coil.
When the coil is placed close to an electrically conductive material, an eddy current is induced in the material.
If a flaw in the conductive material disturbs the eddy current circulation, the magnetic coupling with the probe is changed and a defect signal can be read by measuring the coil impedance variation.
Stress Corrosion Cracking Solutions
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.
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.
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.
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.
Carbon Steel Surface Examination
The MagnaFORM™ eddy current array solution enables users to inspect through paint and rough surfaces. The dynamic lift-off compensation helps ensure that the sensitivity to surface-breaking defects is maintained on the roughest of welds and corroded areas.
