Data Acquisition Software
The RMS2 software integrates scanner control, data capture, data analysis, and reporting tools. The software displays ultrasonic A-scan, C-scan, thickness measurements, and positional data in real time, with a maximum resolution of 0.5 × 0.5 mm (0.02 × 0.02 in). This information is recorded when a scan is saved. The modular user interface is designed to hide and restore infrequently used controls with a single click, and save specific display layouts for future use. The ultrasonic controls are similar to those on a standard ultrasonic flaw detector, therefore trained ultrasonic operators can quickly become familiar with all the software functions.
C-Scan Layers and A-Scan Gates
The RMS2 software is designed around the concept of C-scan layers, which enables operators to quickly switch between the multiple C-scan views generated during scans. The A-scan trace and the C-scan image are displayed in real time, and you can add multiple A-scan gates to measure between portions of the trace. This means you can measure the signal’s amplitude, the part thickness, the internal surface profile, and the external surface profile simultaneously. After acquiring the scan, you can analyze it again by adjusting gate settings to produce a more accurate C-scan image or highlight particular indications. This powerful tool minimizes the need for re-scans caused by changes in surface conditions or minor setup errors.
A-Scan Processing and Floating Gates
RMS A-scan waveform processing is completely digital, in real time during scans and during post-processing. The system records A-scans in raw unfiltered RF form, which can be processed afterwards, including rectification, filtering, wave smoothing, and noise rejection. This minimizes the setup on site and avoids re-scans caused by incorrect ultrasonic setups. Another feature of the RMS2 software is floating flank gates. The floating gates track to the same percentage of the signal amplitude. This enables signals of much lower amplitude to be picked up, improving the accuracy and increasing the efficiently of data analysis and reporting for greater confidence in inspections.
Ultrasonic B-Scan Amplitude View
The amplitude view shows the B-scan profile in both X and Y dimensions at a selected point in a C-scan. Using the B-scan amplitude view, operators can easily identify any defects or inclusions. C-scans are an effective method of viewing general wall thinning and larger defects, but small pit and inclusion indications can often be difficult to see because of their small surface areas. By reviewing acquisitions in B-scan mode, you can quickly identify and size these potentially critical indications. The software also has a stacked B-scan mode to help with identification of step-wise cracking and defects not aligned with the X and Y scanning directions.
