Sonotron NDT introduces the new ISONIC 3510 - Portable Smart Phased Array Ultrasonic Flaw Detector

Sonotron NDT76, Rehovot, Israel

Very Powerful Superior Performance Extremely Portable Smart Phased Array Ultrasonic Flaw Detector and Recorder with 2 Conventional UT and TOFD Channels

ISONIC 3510 uniquely combines phased array (PA), single- and multi-channel conventional UT, and TOFD modalities providing 100% raw data recording and imaging. Along with the intuitive user interface, portability, lightweight, and battery operation this makes it suitable for all kinds of every-day ultrasonic inspections. The first instruments have been just delivered to the customers who already used the pre-production units in their numerous field trials and real projects.

The new ISONIC 3510 is a successor of the very successful ISONIC 2010 instrument, which is present on the market since more than 6 years ago and became the standard in the significant number of industries around the Globe.

In the ISONIC 3510 PA modality is carried by the fully parallel non-multiplexed 32:32 electronics with independently adjustable emitting and receiving aperture, each may consist of 1...32 elements when operating one PA probe or 1...16 elements per probe in case of operating two PA probes simultaneously: there is no external splitter required for the simultaneous use of 2 PA probes. The 64- and 128-elements PA probes may be used with ISONIC 3510 as well upon they are connected to the corresponding instrument’s terminals through the various miniature extenders expanding the functionality to the fully parallel 1 X 64:64, 2 X 32:32, 1 X 128:128, and 2 X 64:64 modes with no multiplexing involved (depending on the type and quantity of the extenders). The groups of PA probe elements composing the emitting and receiving aperture are freely adjustable and may be fully or partially matching or totally separated allowing the flexible managing of the incidence angles, focal distances, types of radiated and received waves including the directly reflected and the diffracted signals either mode converted or not. Each channel is equipped with the own pulser-receiver and A/D converter. Parallel firing, A/D conversion, and ”on-the-fly” digital phasing are performed for every possible composition and size of the emitting and receiving aperture so the implementing of each focal law is completed within a single pulsing/receiving cycle providing the maximal possible speed of the material coverage.

In addition to the PA electronics ISONIC 3510 carries 2 independent conventional channels for implementing of the regular UT and TOFD inspection; each conventional channel is capable for both single and dual modes of use.

The top level ultrasonic performance is achieved through the firing of PA, TOFD, and conventional probes with the bipolar square wave initial pulse with wide-range-tunable duration and amplitude (up to 300 Vpp). The high stability of the initial pulse amplitude within entire duration of the positive and negative half-waves, the extremely short boosted rising and falling edges and the automatic adaptive damping improve the signal to noise ratio and resolution allowing controlling of the analogue gain over the 0…100 dB range for each modality

As its well-known predecessors ISONIC 2010 and ISONIC 2009 UPA Scope the new ISONIC 3510 is a powerful platform for the huge number of the practical PA UT applications available for the activation at any moment. Thanks to the unique True-To-Geometry Volume Overlap Coverage and Real Time Imaging the ISONIC 3510 is suitable for the high performance inspection of the simple and complex geometry welds (butt, longitudinal, fillet, lap, corner, elbow, etc) with scanning from one or both sides simultaneously (if applicable), bolts, bridge hanger pins, wind turbine and other shafts, annular rings, flanges, railway axles and wheels, CRFP and GRFP composite panels and profiled stuff, and the like. The precise and easy reproducible automatic Equalizing of the Sensitivity within Entire Cross-Section / Volume of the Material is provided by the unique TCG-independent angle gain / gain per focal law compensation solution along with the DAC / TCG image normalization. Thanks to the above noted True-To-Geometry Volume Overlap Coverage and Imaging and Equalizing of the Sensitivity within Entire Cross-Section / Volume of the Material the inspection results produced by the ISONIC 3510 and its predecessors are easy interpretable and well acceptable by the UT Pros and non-Pros as well.

Within launching of the new ISONIC 3510 Sonotron NDT doesn’t discontinue its direct predecessor ISONIC 2010 yet as today the ISONIC 2010 is figured in the numerous inspection procedures and norms for the various industries and countries as a standard tool. On the other hand ISONIC 3510 is much more powerful platform, which will bring the PA UT inspection to the new reliability and performance level thanks to the abilities of:

  • being integrated into the robotized systems
  • automatic real time adopting of the sequence of the focal laws to be implemented (scan plan) to the automatically sensed material properties and geometry at every point of the PA probe’s trace
  • comprising the PA and visual inspection video into the same inspection report
  • automatic defect pattern recognition and sizing
  • non-linear acoustics approach to the resolving of inspection task related to the non-ultrasound-friendly materials
  • SRUT guided wave inspection with PA probes
  • etc

In order to smooth the switch to the new platform ISONIC 3510 keeps the ability of uploading and use of the calibrations and results files created with use of its predecessors ISONIC 2010 and ISONIC 2009 UPA Scope and repeating of the test results with the same type PA probes providing the same performance at least.

The lifetime free software upgrade policy is provided for ISONIC 3510 as for all other instruments from Sonotron NDT. The freely distributable ISONIC PA Office software package for PC allows performing of the comprehensive postprocessing including off-line raw data recovery and analysis, defects evaluation, etc, and composing of the inspection reports in the hard copy or soft MS Word®, MS Excel® formats.

ISONIC 3510 is packed into the IP 65 reinforced plastic case with no intake air or any other cooling means required. The large 800X600 pixels 8.5” bright screen provides fine resolution and visibility for all types of inspection data presentation at strong ambient light along with the optimized power consumption rate for the outdoor operation.
