Evident Scientific Dual Element Transducer DHC706-RM

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)
