Phased-array probe

for corrosion detectioninspection

The Dual Linear Array™ probe for corrosion inspection provides many advantages over conventional ultrasonic dual element transducers. This phased array solution improves productivity through features such as larger beam coverage, faster scan speed, and C-scan imaging with increased data-point density. The pitch-catch technique used by this new probe offers better near-surface resolution and pit detection in corrosion survey applications than standard phased array pulse-echo, improving the probability of detection of critical wall thinning.  Thanks to new features, such as built-in irrigation and a replaceable delay line that can be contoured to better adapt to pipe curvature, the DLA corrosion probe can now be used to perform automated inspection. Probe Benefits and Features • Detect defects as shallow as 1 mm (0.04 in.) below the surface. • Cost-effective replaceable delay line. • Built-in irrigation. • High temperature option to scan hot surfaces. • Beam coverage width of up to 30 mm (1.18 in.). • Versatile quick adjustment system adapts to diameters from 4 in. to flat. • Durable carbide wear plates protect the wedge. • Typical inspection depth of 1 to 80 mm in carbon steel. • OmniScan® configuration files (MX, MX2, and SX) on a USB key. OmniScan Software Features • Side, end, and top view imaging (B-scan, D -scan, C-scan). • Full high-resolution A-scan storage. • Two configurable detection gates. • Offline analysis on an OmniScan flaw detector or a computer using OmniPC™ software. New Features, New Possibilities The combination of the DLA corrosion probe and the OmniScan SX flaw detector is an affordable inspection option.
