Pulsed Eddy Current Array (PECA) Probe

Enhance Productivity—Pulsed Eddy Current Array (PECA)

The standard pulsed eddy current array (PECA) probe is specifically engineered to maximize productivity for the detection of Corrosion Under Insulation (CUI) and Corrosion Under Fireproofing (CUF) in pipes, vessels, sphere legs, and more.


The groundbreaking PECA probe makes CUI and CUF inspections as much as 10 times faster than single-element PEC probes! The six-channel array probe can be configured to inspect external diameters from 152 mm (6 in) to flat surfaces. It supports wall thicknesses 6–25 mm (0.25–1.0 in), insulation 0–102 mm (0–4 in) (fiberglass, plastic wrap, concrete, and any non-ferrous material), and inspections through stainless steel and aluminum weather jackets.

Never Been this Fast

The 6-element PECA probe is capable of a single-pass coverage of 457 mm (18 in). The wide coverage does not only makes inspections faster than ever but also minimizes inspection preparation with Grid-As-U-Go™. The coverage and accessory dramatically reduce gridding times compared to typical, single-element PEC. Displaying C-scans has never been this fast, improving the overall productivity of inspections as much as 10 times!
