Designed for performance and reliability

Piezocomposite material

Specially-designed piezocomposite material is inserted in each type of probe. The composite components and geometry are defined according to the temporal and frequency response specifications, while retaining high sensitivity and signal-to-noise ratio level. For phased array probes, the piezocomposite material is also designed to lower the cross-coupling between adjoining elements, which is necessary to properly steer the beam with electronic delay laws. Typical cross-coupling is lower than –30dB.

Matching layer

Taking into account the conditions of use of the probe (manual, automated, direct contact, contact with a wedge), the matching layer is designed to optimize the transfer of energy, to shorten the pulse length and to be wear-resistant.

Backing material

The backing material is designed to shorten the pulse length and to attenuate the back echo. Specially-designed backing materials allow an interesting compromise with high damping and high attenuation in reduced dimensions.


The housing is designed to combine the required geometry with the strength and watertightness of the probe.


Performance of the cable is also a key parameter for the overall performance of the probe. Its attenuation must be as low as possible, in particular for high frequency probes. Its electrical impedance is matched with the probe and electronic characteristics. The bending capability is optimized to access small areas, while keeping high mechanical resistance and constant electrical properties.

The connector is most often defined by the electronic system the transducer will be connected to. However, it must be adapted to handling and environmental constraints (frequency of handling, immersion, vibrations, etc), while guaranteeing consistent quality for the electrical contacts.
