Phased Array Wheel Probe
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
- Offered in two sizes with a 51.2 mm or 128 mm beam width.
- Exceptional coupling with minimal couplant.
- Acoustic impedance similar to water.
- 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
- Built-in laser guide facilitates straight, precise one-line scans
Advanced tire
- Exceptional coupling
- Tire’s unique material closely matches the acoustic impedance of water, enabling efficient transmission of ultrasound energy to the part
- Transparent tire makes it easier to spot air bubbles or contaminants in the water chamber
