SONATEST WheelProbe 2 (WP2)

SONATEST WheelProbe 2 (WP2)

Phased Array Wheel Probe for Corrosion Mapping, Marine Inspection, Aerospace Fuselage Inspection, Aerospace Large Area scanning, and Automotive Testing.

As the best alternative to immersion inspection, the WheelProbe 2 offers an impressive 1mm near surface resolution in the latest composite materials using a 5MHz array. Available also with 10MHz, 3.5MHz and 2MHz versions, the WP2 is capable of measuring flaws in other more attenuating materials. Weighing only 1Kg and 45% lighter than the earlier generation, this more versatile model offers distinct advantages for the operator, especially when scanning large areas upside down.

The WheelProbe 2 is proving to be unrivalled in the field of composite inspection and corrosion monitoring in terms of speed and ease of use, in addition to achieving excellent results.

Typical applications included: Corrosion Mapping, Marine Inspection, Aerospace Fuselage, Aerospace Large Area scanning and Automotive Testing.

Composite Inspection

WP2 presents the most efficient solution for scanning large areas of composite. As the best alternative to immersion inspection of the WP2 offers impressive 1mm near surface resolution in the latest composite materials using 5MHz array. Available also with 10MHz, 3.5MHz and a 2.5MHz version, the WP2 tyre tightly matches the acoustic impedance of water and like its predecessor, produces UT signals of exceptional quality. The configurable handles, adjustable laser guidance, unique LED’s for alarm feedback, remote control with start/stop indexing and reset buttons as well as the remote display makes this package unique, superior and still unequaled.

Corrosion Monitoring

Making complete and reliable surveys to generate corrosion maps is more than a trend, it is required. With the efficiency, performance and precision provided by the WP2, it is now possible to inspect large areas and quickly analyse data to determine if any critical or urgent action is required. Moreover, this technique allows the user to compare large amounts of data over time to perform preventative maintenance, reducing potential downtown. With WP2 the level of confidence is significally increased since decisions can be based on data sets that are 1000 times more detailed, yet still gathered in the same time required to do ‘spot check’ using traditional methods. Whether for axial or longitudinal inspection using unique grooved rollers, or attached to a scanner, WP2’s flexibility makes the tool of choice for a fast and accurate corrosion monitoring application!


WP2 has been re-designed from the ground up in lightweight aluminium-reinforced polymer. Lighter to reduce operator fatigue, and tougher, to give longer service life. Which means you can trust it to perform, day after day, even on the most awkward inspection tasks.


With LED feedback built-in and the optional display attachment, the technician can now focus on obtaining high-quality, consistent UT data. Real time feedback of alarms gives a great feeling of confidence that the inspection is good, and so is the part.


Make the best use of your WP2, and connect it to just about any UT system. With interchangeable cables, you have the best of all worlds. A longer cable? A different connector? These options can be held in stock at very little cost, ready for the jobs as they arrive.


With a choice of either a single ‘joy-stick’ or a crossbar handle, the angle can be adjusted for operator comfort, and with the remote control available for either left or right-handed operation, the ergonomics of this WP2 are unsurpassed.

Roller Options

With the profiled, flat and precision roller options, a few moments’ effort converts your WP2 from a flat-surface composite inspection tool, to a radial or axial pipe corrosion mapping system. Able to scan right to the edges of the part, convex, concave and even irregular surface area are catered for.

Laser Guidance

Keeping your scans on track, the laser pointer option gives a high degree of confidence in the correct registration of the WP2 for multiple pass scans, as well as on longer runs across large surfaces.
