Achieving improved operability and high-precision non-destructive testing.
■ The simultaneous display of three modes (A, B, C scopes) makes defect determination easier.
■ You can select a frequency suitable for the work (high-performance polymer concave ultrasonic transducer).
■ A Scope
This represents the received sound pressure at the transducer and the propagation time of the ultrasound in a rectangular coordinate system. It allows you to grasp the reflected sound pressure from abnormal areas and the depth from the testing surface.
■ B Scope - Cross-sectional Image
The A Scope waveform is represented as a line through brightness modulation, plotted in a rectangular coordinate system with the position (1D) on the sample under the transducer and the sound wave propagation time. The distribution, presence, and depth of abnormal areas under the transducer's scanning line are displayed, allowing for an intuitive understanding of the cross-sectional view.
■ C Scope - Planar Image
The presence or absence of abnormal areas or reflected sound pressure under the transducer is brightness modulated (corresponding to taking a point on the sound wave propagation time axis of the B Scope image), plotted in a rectangular coordinate system with the position (2D) on the sample under the transducer. This method involves setting a gate or sampling point on the sound wave propagation time axis before recording and displaying. It provides a clear understanding of the distribution of planar abnormalities, making it suitable for testing flat materials. By changing the slice level, you can also determine changes in defect depth direction.
