- 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
- Innovative bi-polar square wave pulser with tunable pulse duration and amplitude provides optimal probe driving enhancing 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 or amplitude of bi-polar square wave initial pulse is improper thanks to probe damage prevention circuit automatically limiting energy transmitted to the probe's crystal
- 32-Taps FIR band pass digital filter with controllable lower and upper frequency limits optimizes signal to noise ratio for various probes, materials, and inspection tasks
- 46 dB dynamic range 20 dB/ตs maximum slope multiple curve DAC/TCG may be created using up to 40 data points to correct distance amplitude variations of ultrasonic signals

Multi Channel
Multi-Channel Pulsing Receiving
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, signal digitizing, and recording by up to 8 channels. Measures avoiding cross talking to be taken while placing simultaneously fired probes on the object under test the probes must be well separated
Most compact probes placement on the object under test with complete avoiding of cross talking is provided through pulsing, receiving, signal digitizing, and recording channels separately in time in a sequence loop (sequentially). Sequential pulsing-receiving also saves battery life
Various color combinations may be used for each channel A-Scan. This provides easy distinguishing between channels for multiple A-Scan observations
Two types of calibration files created by ISONIC 2008 may contain settings either for single channel or for all 8 channels simultaneously
|
Multi-Channel Recording
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 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. TOFD strip is also useful for recording CHIME inspection and for some applications where obtaining of RF B-Scan is necessary
|
|
|
256 Colors Palette Map Strip represents sequence of A-Scans whereas color of points for each horizontal line is coded according to corresponding signal level
Main use Map Strip is recording of pulse echo inspections using either longitudinal, shear, surface, or guided waves
|
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 level
Width of gray Time of Flight (TOF) Rectangle is proportional to the signal position in the Gate. For signals, whichs time of flight measurement point matches with the Gate end width of gray TOF Rectangle is equal to the full strip width
For defects signals followed by strong geometry echoes Amplitude Line may represent either first or maximal signal amplitude depending on operator's choice while width of gray Time of Flight (TOF) Rectangle will represent position of the first signal crossing gate level
Amplitude / TOF Pulse Echo Strip may be used for thickness/corrosion profiling and for various flaw detection tasks
|
|
|
Coupling Strip is formed through comparing amplitude of reference signal with the gate threshold. Green Sufficient Coupling
record is provided for signals exceeding gate threshold; red Insufficient Coupling record is provided in opposite case
|
Both time-based and true-to-location strip chart creating is available. For true-to-location strip chart forming it is used
built-in incremental encoder interface.
Observation of A-Scan is possible for every channel whilst scanning. Strip accompanied with A-Scan is
marked with .
To observe A-Scan related to another strip it is necessary just to click on the strip selected
Position of each probe along scanning line is taken into account while
forming strip chart through use of appropriate offset values keyed in at
pre-scanning stage. Thanks to such feature the same defect detected by
different probes will be indicated at the same longitudinal position in each
corresponding strip
Complete sequences of A-Scans for each strip are
recorded during scanning making ISONIC 2008 inspection fully compatible with
ASME 2235-9 Code Case for radiography replacement and other national and
international codes. Upon scanning is completed strip chart accompanied with
the entire raw data and instrument settings may be stored into a file
|
Postrocessing of Multi-Channel Scanning Data
Postprocessing is featured with:
- Previewing and scrolling of whole strip chart
- Recovery of A-Scans for each channel through simple placement of cross-hair cursor above channel's strip
- Composing combination of simultaneously visible strips
- Conversion of any Map Strip into Amplitude / TOF Pulse Echo Strip and reversal
- Varying Region of Interest (Gate) settings for every Amplitude / TOF Pulse Echo Strip
- Marking defects and generating of Strip Chart Inspection Report
- 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
|
|
Remote Control and Data Acquisition
Usual Solution - Use of Umbilical
|
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
umbilical
So 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 is available at last. Thanks to low weight and compact size ISONIC
2008 may be easy fitted into a scanner and connected to probes and position encoder using short umbilical. In that case full remote control of ISONIC
2008 and observation of A-Scans and strip chart in real time may be performed through a PC. Communication between ISONIC 2008 instrument and
remote PC may be provided using cheap and reliable crossover Ethernet cable of up to 200 meters length. It is important that there is no need in special
software to be installed in the remote PC just standard Windows XP or Vista operating system
Optional software and hardware drivers for control of automatic scanner motor are available
