Ultrasonic array roller probe

R-Evolution is an ultrasonic phased array probe housed in a lightweight glycerine-filled roller, delivering fast immersion quality C-scan inspections in the palm of your hand. Designed to minimise operator fatigue, R-Evolution is small and light making it ideal for use in large areas and particularly in overhead inspections.


Typical applications for R-Evolution include

  • Aerospace – In-service c-scans, Bond Inspection, Delamination, or defect detection in composites
  • Wind Energy – Blade spar, leading and trailing edge bond inspection
  • Pipelines and Vessels – Corrosion mapping, Bond testing on overlapping joints

Ergonomic in design, R-Evolution contains an ultrasonic array probe, mounted in a small diameter, glycerin-filled roller. With its durable thin tyre, high-frequency probes can be used to give excellent near-surface resolution enabling the inspection of thin components.

R-Evolution’s buggy self-normalises on curved surfaces ensuring the array is perpendicular without adjustment. The array angle can additionally be easily fine-tuned externally.

The buggy handle features two line lasers for guidance and buttons that can be configured with appropriate instruments to start, stop or increment scans.

R-Evolution has a single axis encoder for inspecting c-scan strips or can be attached to the Phoenix Tracer for a versatile and portable large area c-scan inspection system
