OmniScan MX UT

OmniScan MX UT

The OmniScan MX UT performs conventional UT and automated inspections and supports TOFD as well as encoded B-scan and C-scan, and full data storage. Allows inspections that simultaneously combine TOFD with conventional pulse echo.

Ultrasound Inspection

Time-of-Flight Diffraction Testing

Time of Flight Diffraction Testing with OmniScan

Time-of-flight diffraction (TOFD) is a technique that uses two probes in pitch-catch mode. TOFD detects and records signals diffracted from defect tips allowing both detection and sizing. The TOFD data is displayed in a grayscale B-scan view. TOFD offers wide coverage and amplitude-independent sizing complying with the ASME‑2235 code.

  • One-line scan for full-volume inspection
  • Setup independent of weld configuration
  • Very sensitive to all kinds of defects and unaffected by defect orientation

TOFD and Pulse-Echo Testing

While TOFD is a very powerful and efficient technique, its coverage is limited as a result of two inspection dead zones: one dead zone is near the surface, the other is at the backwall.

The OmniScan® UT allows inspections that simultaneously combine TOFD with conventional pulse echo. Pulse echo complements TOFD, covering the dead zones.

  • TOFD inspection
  • 45º pulse echo for weld cap inspection on either side of the weld
  • 60º pulse echo for weld root inspection on either side of the weld

0‑Degree Testing (Corrosion and Composite)

0-degree testing measures the time-of-flight and amplitude of ultrasonic echoes reflecting from the part into gates in order to detect and measure defects.

  • C‑scan imaging
  • Full A‑scan recording with C‑scan postprocessing

Full-Featured C‑Scan

OmniScan MX UT C-Scan screen

  • Monitors amplitude, peak position, crossing level position, and thickness on each gate.
  • Automatic gate synchronizes from previous gate for higher dynamic range of thickness.
  • A‑scan data storage and C‑scan postprocessing capabilities
  • Optional IF gate for surface-following synchronization or measurement gate, or TCG/DAC curves
  • Positive or negative gate on RF signal (independent for each gate)
  • Eight completely configurable alarms on single-gate events or multiple-gate events, filter for n occurrences from one or multiple channels
  • Customizable color palette for amplitude and thickness C‑scans
  • Adjustable 256-level color palette
  • 2‑axis mechanical encoding with data-acquisition synchronization on mechanical movement
  • Optional data library to access A‑scans and/or C‑scans on PCs for custom processing

Full-Featured B‑Scan

  • Easy-to-interpret cross-sectional view of inspected part
  • Excellent display of corrosion mapping for boilers, pipes, and storage tanks
  • Visual identification of acquired thickness values
  • Encoded TOFD capability for amplitude-independant defect sizing
