EASTWEST ENGINEERING & ELECTRONICS CO. manufactures and offers Ultrasonic Transducers. A transducer is a machine that converts energy from one form to another form. Ultrasonic transducers convert electrical energy into high incidence sound energy and vice versa.

Transducers naturally used for ultrasonic flaw detection utilizes an active element made up of piezoelectric ceramic, composite, or polymer. When this element is keyed up by a high voltage electrical pulse. It vibrates across a specific range of frequencies and generates a burst of sound waves. When it is vibrated by an incoming sound wave, it generates an electrical pulse.

A combine gel is used normally between the transducer and the test piece since sound energy at ultrasonic frequencies does not travel efficiently through gasses.

Types of ultrasonic transducers normally used in flaw detection applications:

1. Contact Transducers
2. Angle Beam Transducers
3. Delay Line Transducers
4. Immersion Transducers
5. Dual Element Transducers
