Modsonic Da Vinci Delta Imaging Ultrasonic Flaw Detector
High-end imaging ultrasonic flaw detector integrating single-channel Time-of-Flight-Diffraction (TOFD), encoded B-Scan, and modified C-Scan in addition to conventional pulse-echo testing. Designed for critical weld inspection in lieu of radiography.
Key Inspection Modalities
Combines conventional flaw detection, Time of Flight Diffraction (TOFD), and corrosion mapping into one field instrument.
Single Channel TOFD
Uses sound diffraction at defect tips for accurate flaw height/depth sizing. Real-time RF A-scan display with auto-scrolling TOFD D-Scan and AsaiView post-analysis software.
Encoded B-Scan & C-Scan
Connect optical encoders for positional mapping and thickness survey. Auto tracking for immersion testing and through-coating/oxide scale thickness logging.
DAC, DGS, TCG & AWS
Full suite of defect evaluation tools including Dynamic DAC as per ASME/JIS, on-board DGS/AVG with ERS readout, Time Corrected Gain (TCG), and AWS D1.1/D1.5 weld ratings.
