Non-destructive testing
Delivering faster, smarter, and more accurate defect detection
Powered by advanced NDT technologies and intelligent automation
Next-gen roll inspection with ultimate precision
Real-time NDT systems with Eddy Current, Ultrasonic, and Surface Wave tech
Our NDT software and hardware platform powers a new generation of automated roll inspection systems, integrating Eddy Current, Ultrasonic, and Surface Wave technologies to detect surface and near-surface defects with high precision. This platform offers real-time results, faster calibration, and intelligent probe positioning to deliver unmatched inspection speed, accuracy, and operational efficiency across the entire testing process.
software platform
Fast, accurate surface defect detection—built into the grinding process.
LRI-E system is our latest technology that uses Eddy Current technology to detect surface defects. It uses our intelligent probe positioning system (IPPS) and the LRI platform. With the LRI-E system, test results are displayed in real-time and, in most cases, Eddy Current surface inspection can be done during grinding.
Our entire line of LRI systems has an improved probability of detection, shorter inspection times, increased data presentation resolutions, faster installations, easier calibrations, fewer parts, and quicker information scanning capabilities.
Reliable surface inspection, with defect types visual checks can miss.
The ET Tester—based on Eddy Current technology—detects surface defects, providing an advantage over visual inspection. It works with a probe positioning system (PPS) and our LRI platform. Our LRI software is an integrated part of the ET Tester and can display two main types of defects, spalls (e.g. cracks) and hardness and/or structural changes (e.g. pinches & bruises).

and surface wave technologies
Comprehensive surface and sub-surface defect detection in one smart system.
Inspection systems equipped with both LRI-E and LRI-U technologies are often combined with Ultrasonic Surface Wave technology to form the LRI-EU (S) automatic roll inspection system. This system is used as a comprehensive testing solution that can detect defects that go unnoticed by standard Eddy Current technology or standard Ultrasonic technology, such as defects that are often on, too close to, or just beneath the surface of the roll.
