LYNCS
Modular manual ultrasonic scanners provide encoded probe positioning for corrosion mapping and weld, flange and nozzle inspection across application-specific configurations.

Product overview
This family of manual and semi-automated ultrasonic scanners provides application-specific platforms for corrosion mapping and weld integrity assessment. Modular frames, probe holders and positioning systems support PAUT, TFM and TOFD inspection workflows, with configurations for small-bore tubing, carbon steel, non-ferrous components, hot assets, flanges and nozzles.
The scanners guide ultrasonic probes across the inspection surface while encoders supply position feedback to the inspection instrument. Depending on the configuration, magnetic wheels secure the scanner to ferrous surfaces, adjustable chains accommodate ferrous or non-ferrous components, or an XY frame tracks both scan and index movement for corrosion mapping. The XY solution supports localized immersion using an Aquablock waterbox, linear arrays with a 0L wedge and dual linear arrays.
Application-specific designs address different access and operating requirements. The small-bore scanner requires 11mm (0.43in) radial clearance for the scanner alone, excluding transducers and wedges, while the high-temperature configuration supports online weld inspection at temperatures up to 350°C (662°F). Flange scanning from the tapered neck is described as providing complete sealing-face coverage, and the nozzle configuration adds encoded skew and probe-position feedback.
Entry-level versions offer encoded PA or TOFD probe positioning on ferrous piping and vessels, with modular conversion to a non-ferrous chain scanner. A separate compact encoder scanner uses a universal clamp to hold probe and wedge combinations and permits one-handed operation in restricted spaces.
Key capabilities
Application-specific modularity
Scanner configurations address corrosion mapping, welds, flanges and nozzles with adjustable frames and probe holders.
Low-profile small-bore scanning
Snap-together links adapt the small-bore scanner to different pipe diameters with single- or dual-probe configurations.
Encoded XY mapping
The lightweight fixed-frame corrosion scanner includes scan-axis and index-axis encoders for accurate XY positioning.
Longitudinal and circumferential scanning
The carbon steel long-seam system converts between axial and circumferential weld inspection.
Non-ferrous chain attachment
Quick-link chains support encoded probe movement on ferrous and non-ferrous pipes, vessels and tanks.
High-temperature inspection
The dedicated magnetic scanner supports on-stream weld inspection up to 350°C (662°F) with heat-resistant cable management and an oversized encoder wheel.
Flange-face assessment
An articulating magnetic frame guides one or two phased array probes around flange couplings.
Encoded nozzle positioning
The nozzle scanner combines skew encoding, Y-axis feedback and leadscrew probe positioning.
Entry-level flexibility
The entry-level weld scanner includes PA and TOFD holding arms and can be converted into a non-ferrous chain scanner.
Universal clamp option
A compact encoder scanner holds a range of probe and wedge combinations for one-handed use in confined spaces.
