Piezo-composite Transducers

 Piezo-composite transducers are successfully used to detect and size defects in any opaque material such as steel, ceramics, polymers, composite materials, concrete or welds. 


 CThe success of these transducers is due to the piezo-composite technology which provides a very high level of sensitivity along with a broad band signal. Piezo-composite technology also allows the manufacturing of focused probes without lenses, which gives them a better sensitivity and no stray echoes.


 Les Piezo-composite transducers are proposed either in the immersion, contact or TOFD technique. They can be produced with very large frequency domains and large sizes.
