Ultrasonic flaw detector adds phased array functionality

0

Sonatest’s new Prisma ultrasonic flaw detector, works as a conventional flaw detector (with or without TOFD), or as a flaw detector with the added functionality of Phased Array.

The Prisma UT is an advanced portable ultrasonic flaw detector which shares much of the basic performance of the popular Sonatest Masterscan series. Above and beyond the Masterscan, it has two independent ultrasound channels with full waveform data recording and 2 axis encoding. The unit also has interface triggering capability with a fast PRF to allow use in high speed immersion, C-Scan applications. The Prisma UT also provides superior state-of-the-art imaging allowing A, B and C scan displays to be viewed simultaneously with a multiple choice of display layouts taking advantage of the 8192 display resolution.

By adding the TOFD software option the Prisma UT has even greater inspection and imaging capability with no pre-amp required and lateral wave straightening and lateral wave removal featured. In addition, the 16/16 phased array option can be selected which increases the probability of detection and also improves productivity significantly.

The Prisma UT with phased array can show A-Scans, B-Scans, C-Scans in UT or PA. The user can add S or L-Scans in PA, as well as end view and true top view. Other views available include: weld overlay, skip cursors, ray tracing, gates that are highlighted in S-Scans, and many more. In addition, there is the 3D scan plan feature which includes part, weld, wedge, probe and scan coverage. This feature assists with the setup and assessment of results.

The Sonatest Prisma is sold at a low entry price and is configured to the platform needed by the user with in field upgrade feature unlock keys. The entry level platform has two independent ultrasound channels with full waveform data recording, 2 axis encoding and beam visualisation set-up tools. The options are as follows: ToFD, manual 16:16 Phased Array (PA), scan axis encoding and recoding for PA, second axis encoding for PA, Interface trigger (IFT) for PA, 16:64 PA.
