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)

Flush Case Dual Transducers

• Metal wear ring extends transducer life
• Wear indicator references when transducer face needs resurfacing
• Knurled, 303 stainless steel case
• Replaceable cable design (special dual cables with strain relief available)
