Single element transducers
Single element and annular array transducers for mechanical probes offer a very high image quality for low overall cost by saving dozen of acoustic and eletronic channels.
The typical performances of this type of transducers are :
- High sensitivity : loop gain up to -12dB
- High bandwidth 70% and more
- Direct mechanical focusing for accurate beam width
- Long term resistance to probes coupling liquid and to mechanical oscillations : no performance variation checked after 6 years of use
