Transmission / separate reception transducers

Translators transmission / reception separate consist of two piezo-electric elements inserted in the same housing and separated by an acoustic partition. One element transmits longitudinal waves; the other member receives the reflected waves in the material.

Benefits:

• Improve the resolution as the input surface Eliminate duplication of delay line echoes in the case of high temperature applications Reduce the input noise on rough surfaces Allow pseudo-focusing effect

Applications:

• Measures residual thicknesses on corroded surfaces
• Corrosion monitoring and erosion
• Detection of craters and pinholes
• Detection of porosity, inclusions, cracks in castings and forgings
