Ultrasonic transducer systems

Ultran has three ultrasonic transducer systems for non-contact inspection of composite structures.

Ultran (College Park, Pa.) has three ultrasonic transducer systems for non-contact inspection of composite structures. The first product, SecondWave M510, is a transducer excitation and amplification system engineered for operating Ultran’s NCU and GMP contact transducers (see below). 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 and statistical process control. Non-Contact Ultrasonic Transducers (NCU) transducers are characterized by high air/gas transduction efficiency, which is sufficient to break the Z (acoustic impedance) barrier for testing of materials without touching them. With Ultran’s M510 system, the NCU transducers are suitable for testing and analysis of uncured and cured composites and sandwich structures. Gas Matrix Piezoelectric Composite (GMP) exhibits high electro-mechanical coupling and is light weight, extremely broadband, exhibits high sensitivity and is said to be well suited for testing highly attenuative materials such as thick composites and porous materials.
