Pulsed Eddy Current Array (PECA) High-Resolution Probe
A high-resolution pulsed eddy current array probe for estimating remaining wall thickness through corrosion scabs and blisters without surface preparation.

Product overview
The PECA-HR probe is designed to estimate remaining wall thickness beneath surface-forming corrosion scabs and blisters. Its dedicated scab inspection solution combines a high-resolution sensor, scanning accessory and processing algorithm, allowing assessment while the asset remains in service without removing corrosion layers or preparing the surface.
An array of dual-coil sensors supports spatial triangulation using pulsed eddy current technology. High-resolution acquisitions and real-time processing with a dedicated scab mode produce C-scan data, while a semi-rigid scab mat maintains constant liftoff during acquisition. Defect detection depends on working within the supported wall-thickness and liftoff ranges.
Operators can use grid acquisition or encoded dynamic scanning, with 75 mm (3 in) coverage per pass. The page states that typical corrosion scabs can be inspected in less than one minute. The solution supports metal thicknesses of 3–19 mm and liftoff of 0–50 mm, providing radiation-free assessment of the remaining ligament.
Key capabilities
Dual-sensor array
Three dual sensors provide six channels and support spatial triangulation.
High-resolution acquisition
The specialized dual-coil sensor design supports high-resolution pulsed eddy current acquisitions.
Single-pass coverage
The array covers 75 mm (3 in) in a single pass.
Two acquisition modes
Grid acquisition and encoded dynamic scanning accommodate different inspection workflows.
Dedicated scab processing
Advanced real-time processing and a dedicated scab mode support corrosion-scab assessment and C-scan generation.
Constant-liftoff mat
A semi-rigid scab mat maintains constant liftoff during acquisition.
In-service assessment
Remaining ligament assessment requires no surface preparation and can be performed while the asset stays in service.
Radiation-free inspection
The technique provides 100% coverage without using radiation.
