Acoustical scanner

Manual and automated building of the TCG curve.Digital filter, allowing to increase considerably the signal/noise ratio.Manual setting of such probe parameters as frequency, prism delay, angle as well as their loading from the probe archive.Except the standart probe frequencies, there is a possibility to adjust frequency softly from 0.4 to 10 MHz with 0.1 MHz step. Features : Built-in feature of ray path displaying (fig.1), providing more accurate determination of the flaw posotion in a tested object. It is used with angle transducers and enables to estimate visually the flaw occurrence depth and position. Except A-scan, the program allows to build B - and D - scans; which are necessary for testing of welded joints as well for estimation of flaw position. A one-coordinate ultrasonic scanner is used to build scans and determine the probe position. Time Of Flight Diffraction (TOFD) method is used to build a D-scan. It allows to detect reliably such flaws as cracks and measure their depth.The analysis of signal spectrum and determination of the reflected signal frequency. Evaluation of the flaw equivalent square is one of the signal processing features implemented in UD4-T.
