Underwater Transmitter Ultrasonic Transducer. Wedge: Device used to direct ultrasonic energy into a test object at an acute angle. It does this by “pinging” (emitting an ultrasonic signal which bounces back to a sensor over the “eyes”). If the transducer is placed flat on a surface to locate defects, the waves will go straight into the material, bounce off a flat back wall and return straight to the transducer. What differentiates this from more traditional methods of ultrasonic testing is that, with LRUT, a liquid couplant between transducers and the surface is not required. The energy that is bounced back by geometric irregularities, such as discontinuities or edges, is picked up by the transducer. 3. APC also offers a 50 kHz power transducer that can be used in a variety of applications, including as a fabric cleaner, nebulizer, atomizer, for ultrasonic mixing, or for cell disruption.
