GENERAL
ISonic 2005 - Inspect and Backup
Portable Digital Ultrasonic Flaw Detector & Recorder
ISONIC 2005 uniquely combines functionality and mobility of a high performance portable digital ultrasonic flaw detector with recording, imaging and data processing capabilities of a smart computerized inspection system
ISONIC 2005 resolves a variety of ultrasonic inspection tasks:
A-Scan-based inspection using conventional pulse echo, back echo attenuation, and through transmission techniques
Straight Line Scanning and Recording:
Thickness Profile B-Scan imaging and recording is performed through continuous capturing of wall thickness readings along probe trace
B-Scan cross-sectional imaging and recording of defects for longitudinal and shear wave inspection is performed through continuous measuring of echo amplitudes and reflectors coordinates along probe trace
CB-Scan horizontal plane-view imaging and recording of defects for shear, surface, and guided wave inspection is performed through continuous measuring of echo amplitudes and reflectors coordinates along probe trace
TOFD Inspection - RF B-Scan and D-Scan Imaging
For Straight Line Scanning and Recording it may be used:
Time-based mode (built-in real time clock)
True-to-location mode (built-in incremental encoder interface)
XY-Scanning and Recording with C-Scan and B-Scan imaging is also possible if using optional USB interface to multi-axis mechanical encoder and appropriate software package
For all types of Straight Line Scanning and XY-Scanning records A-Scans are captured for each probe position along probe trace and may be played back and evaluated off-line at postprocessing stage. This unique feature makes it possible off-line defect characterization through echo-dynamic pattern analysis
Thickness Profile B-Scan Data recorded during Straight Line Scanning is presented in the format compatible with various Risk Based Inspection and Maintenance procedures
ISONIC 2005 has practically unlimited capacity for storing of:
Single A-Scans accompanied with corresponding instrument settings
Ultrasonic signal spectrum graphs (FFT) accompanied with corresponding RF A-Scans and instrument settings
Various A-Scans sequence records along with corresponding Thickness Profiles, B-Scans, CB-Scans or TOFD Maps depending on mode of operation selected; each record is accompanied with corresponding instrument settings

A-SCAN
Conventional pulse echo and through transmission A-Scan-based inspection
640X480 pixels A-Scan display with physical dimensions 130 x 90 mm (5.12" x 3.62") of working area is largest one for the plurality of portable ultrasonic flaw detectors
Combined adjustable spike wave / square wave pulser equipped with variety of probe impedance matching coils provides optimal ultrasound penetration for various materials characterized either by high or low grain, sound attenuation, and the like
High frequency probe may not be destroyed occasionally upon connecting to instrument's firing output even if duration of square wave initial pulse is improperly long thanks to probe damage prevention circuit automatically limiting energy transmitted to probe's crystal
46 dB dynamic range 20 dB/�s maximum slope multiple curve DAC/TCG may be created using up to 40 data points to correct distance - amplitude variations of ultrasonic signals
Both theoretical and experimental DAC may be activated either through keying in dB/mm (dB/") factor or through sequential recording echo amplitudes from variously located equal reflectors
DAC/TCG may be applied to rectified A-Scans (positive, negative, and full wave) and to RF A-Scans as well
Built-in DGS data base for standard probes is unlimitedly expandable
Thanks to extended dynamic range signals significantly exceeding A-Scan height (up to 199.9%) may be evaluated without dropping instrument Gain
Whilst A-Scan is frozen managing of Gain and Gates settings is still allowed and provides bringing signals to necessary evaluation level and performing required evaluation
Dual Ultrasound Velocity Measurement Mode extremely simplifies resolving of sound path distances for dissimilar materials adjacent to each other whereas different values of ultrasound velocity are valid for corresponding signals appearing on the same A-Scan
RF display mode combined with frequency domain signal analysis enhances capabilities of the instrument for materials characterization, bond inspection, testing of dissimilar materials, defect pattern analysis, and probes evaluation
Optional data logger organizes and manages database files capable to store up to 254745 thickness readings each and organized as 2D matrix.
