Contact transducers

These are longitudinal waves translators single piezoelectric element, designed to be applied directly on the surface of the part under examination.

Benefits:

• Protection across the front of the translator increases its wear resistance and impact resistance.
• The translators of this series are recommended for controls in difficult conditions
• Their acoustic impedance is close to that of most metals.
• They can be used on a wide variety of materials.
• Translators Series High Sensitivity “CHF” and those of High Resolution from the series “CHG” meet many requirements acoustic performance.
• Translators High Resolution “CHG” provide better signal / noise ratio for mitigating or dispersing materials.
• Translators High Resolution “CHG” ensure better recovery after the transmit pulse, resulting in better resolution near the surface.

applications:

• For defects with the right translator and measurement of thicknesses.
• Detection and evaluation of delaminations and imperfections.
• Characterisation of materials and measurement of the sound propagation velocity.
• Control plates, billets, bars, forgings, castings or extruded, as well as a large number of other metallic or non materials.
