ISONIC 2008 comprises 8 identical UDS 3-6 pulsing-receiving channels. Most of parameters such as gain, filter settings, pulse duration, display mode, delay, range, ultrasound velocity, etc are individually calibrated per channel. Just firing level (the amplitude of initial pulse) and PRF (pulse repletion frequency) are common for all channels. Every channel may drive either single or dual element probe or probe pair through 2 probe terminals Every channel has its own signal digitizer (A/D Converter)Highest scanning speed may be achieved through simultaneous (parallel) pulsing,receiving,...

Multi-channel record includes few strips of the following types:TOFD Map Amplitude / TOF Pulse Echo Coupling Strips may appear in any combination created by an operator according to inspection procedure. Positioning of the probes in the scanner relatively to each other (the offset) to be keyed in at pre-scanning stage to align the strips > ●● ● ● 256 gray levels TOFD strip represents sequence of RF A-Scans whereas brightness of points for each horizontal line is modulated according to corresponding signal level. Main use TOFD strip is recording of TOFD channels data for weld inspection....

Amplitude / TOF Pulse Echo Strip represents peak amplitude and time of flight for signals matching with Gate and exceeding its threshold level Position of Amplitude Line on the strip is proportional to the signal height. Echo amplitude equal or exceeding 100% of A-Scan height brings Amplitude Line trace to full strip width levelWidth of gray Time of Flight (TOF) Rectangle is proportional to the signal position in the Gate. For signals, whichҒs time of flight measurement point matches with the Gate end width of gray Time of Flight (TOF) Rectangle is equal to the full strip widthFor defects...

● Postprocessing each strip individually using applicable technology either TOFD, CB-Scan, or Thickness Profile including full scope of suitable procedures such as defects sizing, snap-shoots, off-line Gain correction, filtering, etc > ● Converting combination of few strips into thickness, distance or amplitude C-Scan with further C-Scan analysis >

Usually multi-channel inspection is performed with use of manual, semiautomatic, or automatic scanner carrying all probes and position encoder, which are connected to the instrument using long umbilical. This conventional way may be implemented with use of ISONIC 2008, which is capable to drive probes and position encoder through up to 50 meters length umbilicalSo far use of umbilical was accepted by NDT community an no-alternative solution despite low reliability, problems with signal to noise ratio, heavy weight and high cost > An alternative to heavy, noisy, and expensive long umbilical...
