Proven to Perform, Trusted to Deliver

Each OmniScan X4 unit is a complete multitechnology inspection toolbox, enabling you to exploit multiple ultrasonic testing techniques. Leverage its detection and measurement capabilities to accurately identify and evaluate the severity of damage before it becomes critical, protecting welds, components, and assets most susceptible to cracking or corrosion.

Assess with Certainty Using PCI

Eliminate doubt through phase coherence imaging’s capacity to detect and accentuate historically difficult-to-detect flaws, including hook cracks and stress corrosion cracking (SCC). Use PCI to clearly distinguish individual flaws in colonies of fine cracks and characterize them with certainty.

Discover the Advantages of PCI

What Are PCI’s Applications

3x Faster TFM Acquisition Rate

Obtain crisp TFM imaging at up to three times faster* acquisition rates than the predecessor model (X3 64) thanks to the OmniScan X4 series’ improved processing power. Exploit the increased speed and 128-element capacity of the OmniScan X4 64:128PR unit to perform TFM inspections with extended focusing capabilities.

*Achieving this speed depends on the configuration and the use of sparse firing. Inquire for more details.

Gain Instant Insights and Eliminate Inefficency

Twice the Confidence with Twin TFM and PCI

Exploit the individual attributes of PCI and TFM to thoroughly investigate the volume of welds from both sides simultaneously. Use two probes to scan the weld in one pass, displaying TFM and PCI results to compare, measure, and confirm your characterization of indications with efficiency and precision.

Engineered for Speed and Simplicity

Performing phased array, TOFD, TFM, and PCI is straightforward and intuitive on the OmniScan X4 series. Inspectors of any experience level can exploit these techniques with increased efficiency and more confidence utilizing the simple step-by-step scan plan and application presets.

Convenient Application Presets

Improve the learning curve and increase the reliability and consistency of inspections between operators with the OmniScan X4 application presets. Even low-level users and new users can produce an optimal PA or PCI configuration within minutes.

With options for corrosion and composite inspections, these preprogrammed parameters simplify scanning setups using HydroFORM™, FlexoFORM™, and RollerFORM™ scanners, and you can adjust the settings as needed.

Ease Complex Configurations

The OmniScan X4 scan plan’s intuitive step-by-step 3D graphics ease your inspection setups, from the most basic to the most complex.

When setting up your raster scan plan, the scan axes can be customed named and you can create a datum reference point relative to the asset. These real-world references as well as the true orientation correction, greatly ease the creation of an intuitive schematic representation of the inspection data for your report.
