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.
