Patent number: 11841344Abstract: An ultrasonic dry coupled wheel probe with radial transducers emit ultrasound in substantially all radial directions relative to a longitudinal axis. The probe does not require normalization and is efficient in directing ultrasound to a surface being inspected. The probe has a wheel composed of rubber or other materials for acoustically dry coupling the transducer to the surface. A first transducer is composed of a piezoelectric material so that the transducer receives an electrical signal, vibrates, and generates and transmits sound, such as ultrasound. Similarly, a second transducer receives sound such as ultrasound, vibrates, and generates a corresponding electrical signal. The transducer arrangement both transmits ultrasound to the surface and receives the reflection of the ultrasound from the surface. An acoustic barrier separates the transmitting component from the receiving component. The transducer has annular electroplates adjacent to the piezoelectric material.Type: GrantFiled: September 12, 2022Date of Patent: December 12, 2023Assignee: SAUDI ARABIAN OIL COMPANYInventors: Fadl Abdellatif, Sahejad Patel
