Issued: September 23, 2014
Filed: September 23, 2011
Term Extension:  480 days

Inventor: Todd Jackson (Walworth, NY)

A wear cap including a flexible barrel and a rigid disc enables a high-frequency ultrasonic transducer to properly align to the surface of a material to be tested. The wear cap may be employed for any type of contact sensor that requires a protective wear cap and that needs to align to the surface of a material to be tested. An ultrasonic transducer assembly includes a wear cap and an ultrasonic transducer. The ultrasonic transducer is mounted in the wear cap and includes a transducer body with a cylindrical shape. A method of producing a wear cap for an ultrasonic transducer includes selecting a flexible material, forming a flexible barrel from the flexible material, selecting a rigid material, forming a rigid disc from the rigid material, and affixing the rigid disc to an end of the flexible barrel.
