C-Scan Inspection without Immersion The RollerFORM™ phased array wheel probe is used to inspect composites and other smooth-surfaced materials. An affordable and easy-to-implement replacement for full 2D encoding systems, the RollerFORM scanner is a viable alternative to immersion techniques.
The RollerFORM tire’s unique material provides high-quality, immersion-like ultrasonic testing. Minimal couplant and pressure are required to achieve excellent coupling and a strong signal, even in difficult scanning positions.
Features

25 mm water delay line enables inspection of composites up to 50 mm thick.
Can be used in accordance with existing aircraft manufacturer procedures.
Standard Inclusions
Phased array probe with OmniScan connector.
Waterproof encoder.
Laser guide.
Indexer and Start Acquisition buttons.
Filling/spraying pump and tubing.
Just Roll It for Instant Results The RollerFORM scanner, combined with an OmniScan flaw detector, uses zero-degree ultrasonic beams for manufacturing and maintenance inspections. Common applications include delamination sizing and porosity quantification in composite core material, as well as wall-loss monitoring in metals.
The RollerFORM XL scanner’s wider tire and probe offer greater coverage for increased productivity and improved probability of detection (POD). For more attenuative materials, the 1 MHz version of the RollerFORM XL scanner has a larger aperture, which improves the ultrasound beam penetration for challenging applications such as wind blade spar cap and shear web bonding
Ergonomically designed scanner
Integrated indexing button enables you to map inspected surfaces by acquiring multiple one-line C-scans and combining them in real time into a single image
