The OmniScan MX2 2-channel conventional ultrasound module (UT2) can be used for TOFD (Time-of-Flight Diffraction) inspections. It features higher pulser voltages (340 V), increased PRF capabilities, and dramatically improved signal-to-noise ratio.

UT2 TOFD Module and MXU Software

The new OmniScan MX2 UT2 module from Olympus represents a powerful, yet affordable solution for TOFD inspection. Several hardware and software improvements make weld inspection using the TOFD technique faster and easier. Leading class signal-to-noise ratio provides optimum data quality for TOFD inspection.

Improvements

TOFD Wizard
PCS calibration
Crisper B-scan
Multi-TOFD layouts
Lateral Wave straightening
Higher PRF on TOFD groups
Higher voltage (up to 340 V) eliminates the need for preamplifiers

These improvements offer a faster and simpler setup, improved acquisition display, and more accurate defect sizing which improves overall productivity.

Multi-TOFD Layouts

The new Multi-TOFD layout can display more than one group at a time. This allows easy positioning and sizing of flaw indications by visual correlation between groups.

TOFD Screen

Lateral Wave Straightening

The use of the Lateral Wave straightening tool offers a more coherent display for easier interpretation. Lateral Wave straightening also enables more precise depth evaluation and flaw sizing.

Raw TOFD Data

The above mentioned software improvements are also incorporated into the OmniPC software allowing users to analyze data on a PC, while the OmniScan can be redeployed for other data acquisition jobs.

Dedicated Scanners and Accessories

HST-Lite TOFD Scanner

The new HST-Lite scanner is the perfect choice for cost effective, one-channel TOFD inspections when signal quality is important. 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 using only one hand, and will attach to ferromagnetic surfaces even when in an upside-down position.

Stainless Steel TOFD Wedges

The HST-Lite, when bought as a kit, comes standard with the new stainless steel TOFD wedges. These wedges are considered a significant upgrade from the common Rexolite wedges, and a better option for most applications. They offer several advantages, including:

Better wear resistance without the hassle of carbide wear pin adjustment
Better coupling as carbide wear pins can lift the wedge from the surface
Shorter approach (by 3mm) for better coverage of the top of the weld
More rugged for longer life

These wedges are compatible with the Olympus high-performance line of TOFD transducers.

The new stainless steel wedges (on the left) have a shorter approach by 3 mm for better coverage.

TOFD Inspection of Small Pipes

Designed specifically for use with the well-established COBRA scanner, an additional line of TOFD wedges is available for low profile inspections. These wedges can be fitted with 3 mm element diameter ST1 probes to inspect pipes of 1 in. up to 4.5 in. These wedges are available in various longitudinal refracted angles and can be ordered for specific diameters, or from a kit covering the complete diameter range.
