|Major Developments in Ultrasound for Materials Process and Quality Control as well as for
Cost-effective Production, Time and Environment Savings
After 20 years of intense R&D into ultrasound and practical know-how of its interaction with materials,
Ultran has developed the following very significant science and technology for materials testing. We firmly
believe these advancements will help the materials industry and R&D in producing high quality materials,
besides saving cost of production, time, and the environment.
Non-Contact Ultrasound (NCU) transducers varying in frequencies and dimensions
GMP-based contact and immersion transducers varying in frequency and dimensions
Non-Contact Ultrasound (NCU) transducer excitation and amplification system with C-scanning frame.
- NON-CONTACT ULTRASONIC TRANSDUCERS: Known as NCU transducers, they are characterized
by phenomenally high air/gas transduction efficiency, which is sufficient to break the Z (acoustic
impedance) barrier for testing of materials without touching them. Produced from <50 kHz to 5.0
MHz in single and multi-element planar and focused array configurations, NCU transducers are
protected by the US and international patents. With Ultrans M510 system the NCU transducers
are perfectly suitable for testing and analysis of uncured and cured composites, sandwich
structures, green ceramics and powder and light metals, porous, hygroscopic, and touch-sensitive
materials, wood and lumber, pharmaceutical, food and other products.
- GAS MATRIX PIEZOELECTRIC COMPOSITE: Known as GMP, this material exhibits extremely high
electro-mechanical coupling efficiency and is protected by the US and international patents.
GMP is light weight extremely broadband, very high sensitivity, and its manufacturability allows
us to make even very large single element and multi-element arrays. GMP-based transducers are
manufactured from <50 kHz to 500 kHz in NCU and contact transducer designs. These transducers
are well suited to test highly attenuative materials such as concrete, wood, very thick composites,
porous and other materials.
- SecondWave WAVE M510 ULTRASONIC SYSTEM: This novel transducer excitation and amplification system
is specifically engineered for operating NCU and GMP contact transducers. It is offered in single or
multi-channel configuration and can be used to generate C-scan images of materials. M510 is
provided with novel software that is targeted towards materials analysis, statistical process
control, and many other useful functions.
Ultran is a heterogeneous team of dedicated scientists and engineers who have worked very hard to
advance ultrasound to serve the needs of our complex socio-technical world. It is our hope all interested
people will take advantage of this. If you have any questions, please feel free to contact the undersigned.
