Two angled elements create a V-shaped sound path in the test material. This "Pseudo-Focus" enhances resolution in the focal zone. A dual element transducer consists of two crystal elements housed in the same case, separated by an acoustic barrier. One element transmits lon gitudinal waves, and the other element acts as a receiver.

Advantages:

Improves near surface resolution
Eliminates delay line multiples for high temperature applications
Couples well on rough or curved surfaces
Reduces direct back-scattering noise in coarse grained or scattering materials
Combines penetration capabilities of a lower frequency single element transducer with the near surface resolution capabilities of a higher frequency single element transducer
Can be contoured to conform to curved parts

Applications:

Remaining wall thickness measurement
Corrosion/erosion monitoring
Weld overlay and cladding bond/disbond inspection
Detection of porosity, inclusions, cracks, and laminations in castings and forgings
Crack detection in bolts or other cylindrical objects
Maximum temperature capability is 800°F (425°C) for 5.0 MHz and below; 350°F (175°C) for 7.5 MHz and 10 MHz. Recommended duty cycle for surface temperatures from 200°F (90°C) to 800°F (425°C) is ten seconds maximum contact followed by a minimum of one minute air cooling (does not apply to Miniature Tip Dual)
