UD4-T" - reference designation, "Tomographic" -registered trade mark.The ultrasonic flaw detector UD4-T "Tomographic" is a technological know-how that continues a series of the widely used flaw detector-tomograph UD4T (UD4-C), including its conceptual and methodical solutions:Automatic setting of Time Corrected Gain. Probe categorization (measurement of actual parameters of every used probe). Measurement of acoustic properties of testing object materials without using of any additional metrological equipment. Visualization of the defect position within a metal layer or a weld. Direct gaging of equivalent defected area. Evaluation of the defect configuration and sizes. The digital technologies used in the UD4-T "Tomographic" allow to implement in one device a set of different purpose ultrasonic facilities, meeting totally the user requirements. The selection and activation of a separate application software are performed via the user "menu" likewise Windows where every task is a self-contained ultrasonic device: Flaw Detector, Thickness Gauge, Tensometer, etc.The flaw detector UD4-T "Tomographic" also provides the "multitask" mode, when several US applications can work simultaneously (background): some user operating with flaw detection can also work with thickness gauging modes and vice versa.The flaw detector UD4-T "Tomographic" is finely combined with different specialized NDT equipment; it has a wide kit of accompanying accessories: path-control transducer, acoustic scanner, optical system for binding of probe coordinates, as well as other means of coupling and visualization. One of the last development is the video scanner function intended to visualize the testing process in hard-to-reach places. The usage of a video camera enables to display simultaneously the tested area and signal received from the transducer on the device screen. Flexible functionality, simple setting and operation convenience make UD4-T "Tomographic" to an irreplaceable tool for all types of non-destructive testing. It allows to give up the specialized flaw detectors, unify the device base, metrological provision and improve in general the testing accuracy and efficiency. UD4-T "Tomographic" distinctive featuresWide frequency range with fine control from 0,2 to 10MHzTwo independently controlled gates (A and B).Automated or manual setting of Distance Amplitude Correction (till 256 dots).Two signal processing types: rectified and radio.Building and processing the A, B and D (TOFD) scans.Modes: "Waveform", "Freezing" and Ray path display.Windows compatibility of application software.Automated determination of UT velocity within different materials and prism delay.
