ISONIC 2001R / RU
Highly Economical Portable Battery Operated Ultrasonic Testing and Recording Unit
ISONIC 2001R / RU performs all the usual functions of a high-class ultrasonic flaw detector and additionally
provides:
- signal spectrum analysis (FFT) for Bond Testing and Material Characterization
- simple and fast recording and imaging of defects / thickness without any form of encoding device.
The following imaging schemes are observed:
- t-B-Scan (Th) - timed thickness B-Scan - graphically representing thickness profile of the
material under test (cross-section) for fast identification of corroded, laminated or pitted areas
- t-B-Scan (A) - timed amplitude multi-echo B-Scan - graphically representing inspected volume
of the material with amplitude defect responses
- t-TOFD - timed Time of Flight Diffraction Record
At any time it is possible to upgrade the ISONIC 2001R / RU with the appropriate hardware and software,
mechanical encoder or non-mechanical sensors determining the probe location, orientation and coupling
degree, creating a powerful multi-function ultrasonic testing and imaging workstation performing true-to-scale
Scanning Pattern, B-Scan, C-Scan, D-Scan, P-Scan, TOFD and Volume-Scan (3D) presentations.

Enhanced Signal Analysis
Signal Spectrum Analysis (FFT)
FFT Display Mode provides a frequency domain
signal presentation enhancing the evaluation
capabilities.
The typical application utilizing the signal spectrum
analysis is bond inspection of dissimilar materials,
for example skin-to-honeycomb bonding in aircraft
structures, internal glass coating in reservoirs and
reactors, etc.
Frequency domain signal presentation also assists
in crack tip detection, sizing and measurement of
crack length, accurate thickness, ultrasound
velocity and attenuation measurements and routine
ultrasonic probe calibration.
Frequency domain signal presentation is a
standard display mode, which can be activated at
any moment as well as the traditional RF, full or half
wave rectification.
Encoder-Free Recording of the Timed:
Thickness B-Scan Profile
t-B-Scan (Th) - Timed Thickness B-Scan
The t-B-Scan (Th) window represents graphically the back wall profile, allowing easy detection of the wall
thickness minimums caused by pitting, corrosion, lamination, etc. and comparison of the whole recorded data
batch with the user-selected threshold. To control the B-Scan operator adjusts the gate and the scanning time
and length.
Amplitude Multi-Echo B-Scan
t-B-Scan (A) - timed amplitude multi-echo B-Scan
The t-B-Scan (A) window represents graphically the inspected volume with defect indications. All echoes
appearing in the gate are measured and processed simultaneously. Color coding of echo amplitudes may be
either linear with reference to the 50% screen height or DAC / DGS / TCG normalized with reference to the
distance-amplitude curve. There are 3 color scales available: Rainbow, Thermal or Gray. To control the
B-Scan operator adjusts the gate and the scanning time and length.
Y-marker allows measuring of the reflector's depth or MTD for each recorded echo (MTD = Material Travel
Distance).
The typical example of the amplitude t-B-Scan (A) illustrates scanning of a composite material with a
lamination - both effects, namely the reduction of the back echo and appearing of the defect echo are clearly
shown in the recorded image.
TOFD
t-TOFD - timed TOFD
The t-TOFD window represents a traditional TOFD Map comprising all RF signals captured during the
scanning. Active pointers allow reconstructing of each recorded signal along the scan and timing
measurements required for the defects sizing. To control the TOFD record operator adjusts the delay and range
of the A-Scan and the scanning time and length.
