Phased Array Probes and Wedges
A configurable ultrasonic probe and wedge family supporting PAUT, TFM and TOFD for weld inspection, corrosion assessment and complex component testing.

Product overview
Eddyfi Technologies’ Phased Array Probes and Wedges family covers ultrasonic flaw detection, thickness gauging and material research. Linear, matrix, flexible, immersion and contact configurations address different component geometries, with customizable arrays and wedges for application-specific inspection requirements.
The phased array designs use piezocomposite ceramics and electronic control to support inspection resolution and beam steering. TFM probes support imaging based on full matrix capture data, with an algorithm focusing throughout the inspection area. Separate TOFD probes use highly damped broadband transducers to determine crack dimensions in metallic welds, while dual matrix arrays use transmit-receive configurations to improve sensitivity and signal-to-noise ratio in challenging materials.
Application-specific designs include compact probes for restricted access, corrosion arrays for scanning extensive surfaces, flexible arrays for curved metals and composites, and immersion arrays for non-contact inspection. Contact membrane probes provide coupling on threaded bolts and rough surfaces through a replaceable membrane. High-temperature linear probes offer distinct mid- and high-temperature wedge options, while the dual-linear corrosion array is designed for inspections up to 200°C (395°F).
Custom development extends to arrays for tube and bar testing machines, aerospace forgings and carbon-fiber-reinforced polymer corners. In-house design, machining, ceramic fabrication and application engineering support solutions for unusual geometries and demanding inspection tasks.
Key capabilities
Configurable linear arrays
General-purpose arrays offer variation in frequency, element count and pitch for different inspection requirements.
Restricted-access designs
Small-footprint ABFP probes and low-profile A15 and A25 cases address confined spaces and small-diameter pipe inspections.
TOFD crack sizing
Highly damped broadband TOFD transducers feature quick-swap screw-in wedge attachment for metallic weld inspection.
Large-area corrosion scanning
Corrosion arrays reduce inspection time compared with single-element inspections on large plates, bars and other extensive surfaces.
Flexible surface conformity
FlexArray transducers adapt to various radii when inspecting curved metals and composites.
Replaceable contact membrane
Contact membrane probes support coupling on rough surfaces and threaded bolts, with customizable side- or top-mounted cables.
TFM imaging
TFM processing interprets full matrix capture data to focus at all points within the inspection area.
Dual matrix transmit-receive design
Dual matrix arrays combine enhanced sensitivity and signal-to-noise ratio with beam skewing for difficult materials and dissimilar metal welds.
High-temperature configurations
Dedicated linear wedge options and a dual-linear corrosion array address elevated-temperature inspection requirements.
Custom probe development
In-house engineering, machining and ceramic fabrication support specialized array geometries and applications.
