ULTRASONIC TRANSDUCERS Contact High Frequency Shear Wave Dual Element Angle Beam Immersion Pinducers Delay Line Transducer Types General Purpose – GP General purpose transducers are medium damped transducers combining optimum sensitivity without sacrificing near surface resolution. Typical bandwith is 30% to 50% @ -6dB High Resolution – HR High resolution transducers are highly damped, broadband transducers usually chosen for improved near surface resolu- tion, and improved signal to noise. Typical bandwith is 70% to 100% @ -6dB High Power – HP High power transducers are lightly damped or air-backed narrowband transducers de- signed for maximum power & penetration. They can be configured for use with tone burst or CW pulsers. Typical bandwith is 10% to 40% @ -6dB 508-435-6831 • 800-982-5737 • www.ctscorp.com • [email protected] Contact Transducers Contact Transducers are the most common and frequently used to introduce longitudinal waves into a material. Also, by using special elements, normal incidence shear wave or a combination of longitudinal/shear wave transducers can be made. These types of transducers are used in direct contact with the test material and therefore require a highly durable wearplate. Contact Transducers are single element transducers designed for general- purpose contact inspection of metal, ceramic, and composite materials. These transducers offer rugged construction and maximum resistance against fracture and rough surfaces. Advantages: • Thick walled, case-hardened chrome-plated cases for standard contacts • Compatible with all commercial flaw detectors • Delrin sleeves for fingertip styles reduces case noise • Available in high sensitivity, high resolution and general purpose Standard Contact Transducers The Standard Contact Transducer case styles offer thicker walled, case for extended life wear. They are offered in side or top BNC mounted connectors.

These Delay Line Transducers are recommended for inspection and thickness gauging of thin materials, and near surface flaw detection. Removable Delay Line Transducers High resolution (HR) Removable Delay Line Transducers are designed for near surface resolution. The versatility of the transducers provides an economical approach and allows a quick change when the delay tip gets worn. Each part is equipped with a screw-on retaining ring and a room temperature low- attenuation delay line material. Other high temperature delay line materials can also be substituted.

CTS designed all of its Angle Beam Transducers with high gain and optimum resolution (GP Series). Special broadband, high resolution transducers (HR Series) can be sub- stituted upon request. All replaceable wedges are offered in standard rexolite or polystyrene depending upon frequency. In addition, special high temperature wedges are available up to 500°F. As an option, CTS can contour Angle Beam wedges for axial or circumferential pipe or bar inspection. Angle Beam Transducers utilize the basic principle of refraction and mode conversion to produce refracted shear or longitudinal waves in the test material. The angle of incidence required to produce the desired refracted wave is calculated from Snell’s Law. The following formula may be used to calculate the wedge angle (Q1) required to generate the desired mode and refracted angle (Q2) in the material under test. SinØ1 V1 = SinØ2 V2 Ø1 = Wedge angle Ø2 = Angle of refracted wave in test material V1 = Longitudinal velocity of wedge material V2 = Velocity of material being inspected for the desired mode AWS Transducers AWS Transducers conform to AWS Code D1.1. The AWS wedges are offered in either Serrated or Snail configurations and provide optimum signal to noise ratios.
