The Olympus OmniScan MX2 with the UT2 module and the OmniScan® SX are powerful yet affordable solutions for TOFD inspection. Representing the latest developments in software and hardware, the OmniScan SX and the UT2 module for the OmniScan MX2 are designed to make weld inspection using the TOFD technique fast and easy. Numerous performance enhancements and a leading-class signal-to-noise ratio provide you with optimum data quality for TOFD inspection.
Key Improvements
When combined, these features offer you a faster and simpler setup, easier results interpretation, and more accurate defect sizing for an overall increase in productivity. |
The lateral wave straightening function has been optimized so that the readability of TOFD results is improved. A straighter lateral wave also enables more precise depth evaluation and flaw sizing.
Raw TOFD Data | TOFD data after lateral wave straightening is applied. |
The new Multi-TOFD layout, offered in the latest OmniScan® MXU software, can display more than one group at a time. This enables you to easily position and size flaw indications by visual correlation between groups.
All of these improved software capabilities have also been incorporated into the OmniPC™ software. This gives you the flexibility to analyze data on a computer, while the OmniScan unit is redeployed to the next data acquisition job.
HST-Lite TOFD ScannerThe HST-Lite scanner is an ideal tool for performing cost-effective, one-channel TOFD inspection with consistent and reliable data quality. The combination of magnetic wheels and spring-loaded probe holders offer the stability required to perform high-quality, one-line inspections. The scanner can be operated with one hand, and it maintains a firm hold on ferromagnetic surfaces even when held upside-down. | |
Stainless Steel TOFD WedgesOlympus offers an HST-Lite scanner kit that comes standard with stainless steel TOFD wedges. For many applications, stainless steel wedges are a better option than common Rexolite wedges as they offer several advantages:
These wedges are compatible with the Olympus line of high-performance TOFD transducers (ST1 case type). | The approach of the stainless steel wedge (on the left) is 3 mm shorter than the Rexolite wedge for better weld coverage |
TOFD Inspection of Small PipesDesigned specifically for use with the COBRA® pipe scanner, an additional line of TOFD wedges is available for small-diameter-pipe weld inspections. These wedges can be fitted with 3 mm element-diameter transducers to inspect pipes measuring from 1 in. to 4.5 in. OD. Olympus ST1 wedges are available in various refracted longitudinal angles, and they can be ordered for specific diameters or in a kit covering the complete diameter range. | The COBRA small-diameter pipe scanner can perform TOFD inspections with the appropriate wedges, cables, and transducers. |
