Olympus NDT Introduces New TOFD Capabilities for the OmniScan MX2
Posted: 2012-11-23
Olympus NDT, a world leader and pioneer in industrial ultrasound phased array
instrumentation, is pleased to introduce the latest hardware and software
advances for the innovative OmniScan MX2 flaw detector. Olympus now offers a
second generation, 2-channel conventional ultrasound module (UT2) that can
be used for TOFD (Time of Flight Diffraction) inspections. Also updated is the
OmniScan MX2's onboard software with numerous TOFD specific improvements
to maximize performance. Together, the new module and software will set a
new industry standard for TOFD inspections. TOFD is a unique ultrasonic
technique that utilizes time based signal information for flaw sizing in place of
a traditional amplitude based sizing approach. TOFD can therefore size defects
more reliably regardless of the orientation of the crack by utilizing the more
consistent time-based information.
The new 2-channel UT module is a completely redesigned hardware platform,
which introduces a host of new improvements as compared to the previous
generation. Higher pulser voltages (340 V), increased PRF capabilities, and
dramatically improved signalto- noise ratio are just a few examples of
enhancements that take the OmniScan MX2 to a new level of TOFD
performance. In addition, a TOFD wizard, a PCS calibration tool, multiple TOFD
screen layouts, Lateral Wave straightening function, and crisper B-scans on the
software side bring faster and simpler setups, improved acquisition displays,
and overall better defect sizing capabilities.
To further complement the OmniScan MX2 TOFD capabilities, Olympus NDT is
pleased to announce an additional dedicated TOFD scanner, the HST-Lite, which
optimizes size, features, and cost where it matters most in TOFD inspections.
Magnetic wheels and spring-loaded probe holders enable one-hand operation
and permit upside-down scanning on ferromagnetic surfaces. While the
addition of the 340 V pulser voltage of the new UT2 module often negates the
need for a preamplifier, the HST-Lite can also accept a scanner-mounted
preamplifier if the specific application setup requires the use of one.
Olympus NDT also offers new stainless steel-framed TOFD wedges that offer
great wear resistance and durability without the need for carbide wear pins, and
superior coupling due to the absence of the carbide wear pins. They also offer a
superior approach distance for closer placement to a weld crown as compared
to common Rexolite wedges. These TOFD wedges have identical transducer
thread patterns to the Rexolite wedges and are compatible with the complete
line of Olympus TOFD transducers.
Lastly, Olympus NDT is pleased to introduce an additional new set of TOFD
wedges for use with the low-profile COBRA scanner. When used with the COBRA
scanner, these Rexolite wedges enable an operator to perform a TOFD
inspection of pipes from 1.00 in. (25.4 mm) to 4.5 in. (114 mm) in areas with
reduced clearance around the circumference of the pipe.
