Conventional single channel pulse echo and through transmission A-Scan-based inspection
640X480 pixels A-Scan display with the physical dimensions of working area 130 x 90 mm (5.12" x 3.62") is the largest one for the
plurality of portable ultrasonic flaw detectors
The bi-polar square wave pulser with the tunable pulse duration and amplitude provides the optimal probe driving enhancing ultrasound penetration for the
various materials characterized either by high or low grain, sound attenuation, and the like
The high frequency probe may not be destroyed occasionally upon connecting to the instrument's firing output even for the improperly settled duration and / or
amplitude of the wave initial pulse thanks to the probe damage prevention circuit automatically limiting the energy transmitted to the probe's crystal
32-Taps FIR band pass digital filter with the controllable lower and upper frequency limits optimizes the signal to noise ratio for various probes, materials, and inspection tasks
46 dB dynamic range 20 dB/µs maximum slope multiple curve DAC/TCG may be created using up to 40 data points
Both the theoretical and experimental DAC may be activated either through keying in the dB/mm (dB/") factor or through recording of the
echo amplitudes from the variously located equal reflectors
DAC/TCG may be applied to the rectified A-Scans (positive, negative, and full wave) and to RF A-Scans as well
The built-in DGS database for the standard probes is unlimitedly expandable
Thanks to the extended dynamic range the signals significantly exceeding the A-Scan height (up to 199.9%) may be evaluated without dropping the Gain
Whilst the A-Scan is frozen managing of the Gain and Gates settings is still allowed and provides bringing the desired signals to the
necessary evaluation level required for the evaluation
The Dual Ultrasound Velocity Measurement Mode extremely simplifies resolving of the sound path distances for dissimilar materials adjacent to each other;
the various ultrasound velocity settings may be applied to the corresponding signals appearing on the same A-Scan
The RF display mode combined with the frequency domain signal analysis (FFT) enhances the instrument’s capabilities for the ultrasonic spectroscopy with the purpose of materials characterization,
bond inspection, testing of dissimilar materials, defect pattern analysis, probes evaluation, etc
Optional data logger organizes and manages database files capable to store up to 254745 thickness readings each and organized as 2D matrix. In
the database every thickness reading is accompanied with the corresponding raw data A-Scan and instrument setup. Automatic creating of MS Excel® thickness spreadsheet meets the
requirements of various Risk Based Inspection and Maintenance (RBIM) procedures

ISONIC 2008 carries 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 settled individually
per channel. Just the Firing Level (the amplitude of the initial pulse) and PRF (Pulse Repletion frequency) are common for all channels. Every channel may drive either single or dual element probe / probe pair
through either 1 or 2 probe terminals
Every channel carries its own signal digitizer (A/D Converter)
The highest scanning speed may be achieved through the parallel pulsing, receiving, signal digitizing, and recording by up to 8 channels; the measures for avoiding of the cross-talking through the material
to be taken whilst placing simultaneously fired probes on the object under test – the probes should be separated properly
Most compact probes placement on the material with no cross-talking may be provided when using the sequential pulsing, receiving, signal digitizing, and recording. Sequential pulsing-receiving also prolongs battery life
There are various color combinations available for distinguishing the channel A-Scans. This is especially useful for the multiple A-Scan observation
There are two types of calibration files that may be created by ISONIC 2008 containing the instrument settings for either one channel or for 8 channels simultaneously
For the number of inspection applications the operators need just to observe several A-Scans simultaneously obtaining an audible alarm in case of finding situation. The typical example of such application is
the multi-channel dual rail inspection, which is illustrated by the video below:

Multi-Channel Recording: Strip Chart
The multi-channel record (strip chart) may include several strips of the following types:
TOFD
Map
Amplitude/TOF Pulse Echo
Coupling
The strips may appear in any combination created by an operator according to the inspection procedure. Positioning of the probes in the scanner relatively to each other – offset – to be keyed in at the
pre-scanning stage - this allows aligning of the strips
The 256 gray levels TOFD strip represents a sequence of RF A-Scans whereas the brightness of points for each horizontal line is modulated according to the corresponding signal level
The main use of the TOFD strip is the recording of TOFD channels data for weld inspection. TOFD strip is also useful for the recording of CHIME inspections and for some other applications
where the observation and recording of RF B-Scan is necessary
The 256 Colors Palette Map Strip represents the sequence of A-Scans whereas the color of points for each horizontal line is coded according to the corresponding signal level
The main use of the Map Strip is the recording of pulse echo inspections using either longitudinal, shear, surface, or guided waves
The Amplitude / TOF Pulse Echo Strip (PE Strip) represents the peak amplitude and the time of flight for signals matching with Gate and exceeding it’s threshold level
The position of the Amplitude Line on the strip is proportional to the signal height. The echo amplitude equal or exceeding 100% of the A-Scan height brings the Amplitude Line trace to the full strip width level
The width of the gray Time of Flight (TOF) Rectangle is proportional to the signal position in the Gate. For the signals, which’s time of flight measurement point matches with the Gate
end width of the gray TOF Rectangle is equal to the full strip width
For the defects signals followed by the strong geometry echoes the Amplitude Line may represent either first or maximal signal amplitude depending on operator's choice while the width of the gray
Time of Flight (TOF) Rectangle will represent the position of the first signal crossing gate level
The Amplitude / TOF Pulse Echo Strip may be used for the thickness/corrosion profiling and for the variety of flaw detection tasks
The Coupling Strip is formed through comparing of the amplitude of the reference signal with the gate threshold. The green Sufficient Coupling
record is provided for the signals exceeding the gate threshold; the red Insufficient Coupling record is provided in the opposite case
Both time-based and true-to-location encoded strip chart creating is available
Observation of the A-Scan is possible for every channel whilst scanning. The strip accompanied with the A-Scan is
marked with . To observe the A-Scan related to another strip it is necessary just to click on it
The position of each probe along the scanning line is counted whilst forming the strip chart through the use of appropriate offset values keyed in at
the pre-scanning stage. As a result the same defect / imperfection detected by the different probes will be indicated at the same longitudinal position in each
corresponding strip
The complete sequences of A-Scans for each strip is recorded during the scanning making the inspection fully compatible with the ASME 2235-9 Code Case for radiography replacement and other national and
international codes. Upon scanning is completed the strip chart accompanied with the entire raw data and instrument settings may be stored into a file
The exemplary videos below illustrate the multichannel weld inspection and in-maintenance inspection of the drilling pipes with the strip chart data recording and imaging:

such as defects sizing, snap-shoots, off-line Gain correction, filtering, etc
Converting the combination of few strips into the thickness, distance or amplitude C-Scan with further C-Scan analysis
ISONIC AVT Scan - Material Thickness Measurement and Recording Based on Automatic Determining of Ultrasound Velocity
For the UT applications related to the thickness probing and recording on the materials with inhomogeneous structure it is
necessary to probe ultrasound velocity at every point of the probe trace prior to taking the thickness reading
Corrosion detection in the paper mills steam drums represents the typical example for such inspection problem, which is resolvable with the use of
ISONIC AVT Scan (Automatic Ultrasound Velocity Determining and Thickness Scanning and Recording) Technology,
which is implemented through the dual channel operation of ISONIC 2008 instrument with use of specially designed AVT Scan probe
The AVT Scan probe carries:
two single element longitudinal wave angle beam transducers for the pitch-cath generating and receiving lateral wave: this signal used for the automatic determining of ultrasound
velocity in the thickness probing point
dual element straight beam transducer for thickness measurement
For the continuous line scanning and recording the AVTScan probe may be fitted into the cart with 4 magnetic wheels, which are easy adjustable to the surface curvature. True-to-location recording
is possible upon the incremental encoder is attached to the scanning cart
Whilst scanning there is 100% raw data caprtuing and recording provided for both channels along with imaging of the thickness profile of the materials and ultrasound velocity distribution along the scanning line
Freely distributable ISONIC AVT Scan PP postprocessing package for the PC allows play back of all captured A-Scans, off-line Gain, Gate manipulation, defects sizing, exporting data into MS Excel®, creating of editable inspection report in MS Word® format, etc
Beside ISONIC 2008 instrument ISONIC AVT Inspection Scan SW Package may run in the PA units, namely: ISONIC 2010 unit equipped with two conventional channels and ISONIC 3510
The inspection pricinples, calibration and scanning process are illustrated by the video below:

UT over IP - Remote Control and Data Acquisition
Thanks to the Client – Server software architecture ISONIC 2008 may be controlled remotely from a regular PC running under Win’XP, 7, 8, 10. There is no need in the special software for that purpose, just download and install in the PC the same software as used in the instrument
The software installed in the PC should be of the same release as the software running in the ISONIC 2008 and correspond to the instrument model
Installing the Instrument Software in the PC
Upon started the installation routine generates the dialogue as below on the PC screen:
It is necessary to check Install client only and uncheck Run on windows startup option then to click on Install button. Further actions are taken by the installation routine automatically
Controlling the Instrument from the PC
The instrument and the computer should be connected to the same LAN or Wi-Fi and obtain the IPs automatically. The initial Startup menu (Start Screen) appearing upon powering the instrument on and booting up completed
should be kept on the unit's screen at the time of establishing the remote connection and control. In the computer the same software should be launched: on appearing of the Startup menu it is necessary to select the instrument
to be controlled from the list of the available Idle units:
Once the connection is established ISONIC 2008 unit enters into the slave mode being connected to the probes and encoder and running the just the server routine while the computer performs full control of the instrument,
data acquisition, processing, and storage on the local drives through running of the client software in the same manner as the instrument does when operating autonomously
ISONIC 2008 carries 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 settled individually
per channel. Just the Firing Level (the amplitude of the initial pulse) and PRF (Pulse Repletion frequency) are common for all channels. Every channel may drive either single or dual element probe / probe pair
through either 1 or 2 probe terminals
. To observe the A-Scan related to another strip it is necessary just to click on it
