Description
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
