Resonic NDT Systems offers highly unique, innovative and patented quality control technology for non-destructive testing of all metals and some composites including exotic alloys, powdered metals and metal matrix composites.
Resonic NDT Systems instrumentation utilizes the patented process of Electro-Magnetic Acoustic Resonance (non-contact) to detect not only surface but subsurface defects & seams, porosity/inclusions, hardness/density changes, alloy identification, plating/cladding integrity and verification of size and/or thickness in as little as .003 seconds.
EMAR (Electro-Magnetic Acoustic Resonance) differs significantly from current Eddy Current and Ultrasonic NDT methods and offers the following advantages over these two methods:
Also, unlike older technology such as RUS (Resonant Ultrasound Spectroscopy), EMAR operates at typically 1 to 15 MHz frequencies in a narrow bandwidth manner. The resonant acoustic field generated by the non-contact RM-EMAT can either be highly localized or “trapped” adjacent to the transducer or allowed to resonate an entire component. In short, EMAR can be “focused” to the task at hand.
To the user, Resonic NDT Systems represent:
Applications for Resonic NDT Systems Electro-Magnetic Acoustic Resonance inspection:
The first of three US Patents for this technology was issued in late 1998. Two additional patents have been recently issued with additional patents pending. Realizing the global market potential international patent filings are in process. These patents are under license to Resonic NDT Systems.
Technological development is continuing and additional IP filings will be pursued as this emerging technology continues to evolve. Patents in use by Resonic NDT include:
(see also corresponding International Filings)
Resonic NDT Systems, Inc. was incorporated in June of 2004 to produce the patented Resonance Mode Electromagnetic Acoustic Transducer (RM-EMAT) and the Acoustic Resonant Inspection System (ARIS) product line. The ARIS system and testing technique are the result of more than a decade of research and development.
Resonic has a long history of research collaboration with NIST.
