The MX-2 is a new mainframe that is compatible with all current phased-array modules. Its features include a 25 cm touch screen, giving a display twice as large and twice as bright as the original Omniscan.

With a touch, this display can be toggled to full screen mode, for better visibility at a distance.

The touch screen allows simple, quick navigation with easier and faster cursor and gate setup. With pop-up virtual keyboards for quick entry of setup names and notes, there’s no need to attach a mouse or keyboard.

    The flaw detector also offers:

  • Faster data transfer to USB and larger standard data file size
  • 300 per cent improved screen refresh rate;
  • Better battery management for longer operation without charging; and,
  • An IP66 rating, and is more rugged than ever, built to withstand drops and spills in demanding test environments.

The MX-2 now comes with all software options as standard, including the multi-group function for the simultaneous running of more than one probe and/or additional focal laws with the same probe. For example, this is useful to run both sectorial and linear scans for weld testing.

The unit has also been fitted with time of flight diffraction that, when added to a phased-array scan, can increase the probability of detection of defects for the small cost of conventional probes and cables.

In addition, the MX-2 includes the New Weld Overlay Wizard, which allows display of the weld geometry and a weld overlay over the sectorial scan. This can assist with defect analysis as shown in Figure 2. When not required, these can be easily turned off.

    As with the original Omniscan, the MX-2 also features:
  • Setup and calibration wizards with clear instructions to guide the user;
  • Code-compliant sensitivity and wedge delay calibrations – every A-scan is calibrated as required by relevant codes such as ASME and API; and,
  • Online help with detailed graphics and definitions.

Pipeline applications

The MX-2 can be used for manual girth-weld scanning, as shown in Image 1.

    It is fully compatible with existing Olympus scanners, including:

  • The HSMT-Compact and HSMT-Flex scanners;
  • Weldrover for automated weld testing;
  • Hydroform for corrosion mapping (as shown in Image 2); and,
  • Cobra scanner for weld-testing in small bore pipe.

The Omniscan system is not compatible with Olympus’ PipeWIZARD system, as this system uses a Focus LT, not an Omniscan, as zone discrimination requires more focal laws than other weld testing techniques.
