1 Ultrasound Redefined Ultrasonic Transducers

2 Introduction Ultran is a team of engineers, scientists, and skilled technicians that works closely with our clients. Together we are dedicated to providing the highest quality products and solutions. Ultran accomplishes this by focusing on the heart of ultrasound: the transducer. Long ago we realized that for ultrasound to rival other wave-based methods, we had to first develop the field. These goals are possible only through transducers with the right acoustics that perform under given conditions of testing. Forty years of non-stop R&D in transducers and applications allows us to share Ultran s milestones with you. Key Developments 1977 Unipolar λ-series transducers for extremely high resolution and spectroscopy Dual damping mechanism for high signal-to-noise ratios Optimum development of broad-band (W-series), medium band, and narrow-band (kseries) transducers from 500 khz to 25 MHz (currently offered up to 10 MHz) Very High Frequency transducers from 30 MHz to 200 MHz (currently discontinued) shear wave propagation transducers from 200 khz to 20 MHz Dry Coupling longitudinal and shear wave transducers from 200 khz to 25 MHz. Introduction of air/gas propagation transducers from 50 khz to 5 MHz High Temperature transducers from 200 khz to 5 MHz for operation >800 C Introduction of Wideband Ultrasonic Spectroscopy High Numerical Aperture transducers up to 150 MHz (currently discontinued) High Power transducers for biomedical therapy and industrial applications from 50 khz and above Very Low Frequency transducers from 30 khz and up High Efficiency Air/Gas Transduction transducers from 30 khz to 10 MHz for practical non-contact ultrasound Gas Matrix Piezoelectric composite transducers for high sensitivity and bandwidth, from 30 khz to 500 khz Array transducer development for high volume production line inspection applications Optimization of medical therapy transducers for low intensity focused ultrasound (LIFU) Development of 2D phased array integrated systems for wearable medicine and NDT structural health monitoring.

4 Transducer Construction Craftsmanship Ultran has strict in-house quality control standards which result in high performance transducers for non-destructive testing and medical therapy applications. Each transducer features careful alignment of acoustic and geometric axes and is encased in its own optimally shaped and sized housing with specially designed acoustically passive materials. Combined with our unique transducer-making technology, these features produce an optimum response from all our acoustic series. Transducer Housing Pulse Control/ Damping Material Encapsulation Noise Control Material Piezoelectric Material Coaxial Connector Electrical Connection Bond Layers Protective/ Impedance Matched Face Elements of a Piezoelectric Transducer A transducer can be as simple as a piezoelectric disc with leads attached to both faces. Or, it can be a complex device intended to evaluate a number of materials and interfaces. In conjunction with the testing environment and a material s physical condition, a transducer device must be characterized by proper acoustics and mechanical construction. Therefore, the design of a modern transducer requires a knowledge of materials and the associated physics. Ultran s years of experience have led to the evolution of an array of transducer designs suitable for a vast number of materials and test conditions. Ultran s transducer designs are protected by international patents 4

5 Transducer Characterization Acoustic Parameters of a Transducer Our transducers are measured and characterized by a number of key parameters which are listed in the table below. Nominal Frequency Peak Frequency Bandwidth Center Frequency (BCF) Bandwidth (BW) This is the target nominal frequency of the transducer as identified by the model number. This is the highest frequency response measured from the frequency spectrum. This is the average of the lowest and highest points at a -6dB level of the frequency spectrum. This is the difference between the highest and lowest frequencies at a -6dB level of the frequency spectrum, also identified as the % of BCF or of PF. Test Setup for Data A report The schematic (bottom left) depicts the water immersion example for characterization of an acoustic transducer. A transducer is characterized by using hard, soft, or gaseous reference media depending upon its design and intended application. The oscilloscope trace (top left) includes the time domain response (top - blue) and frequency spectrum (below red). 5

6 Transducer Characterization Spatial and Acoustic Pressure/Intensity Measurements for Select Transducers For specialized transducers or upon customer request, Ultran may perform spatial beam profile measurements using Ultran s U710x Ultrasonic Analysis System. Measurements are performed using an immersible calibrated hydrophone for immersion transducers. Sample Data for Focused Immersion Transducer The profile images to the right were captured for a focused immersion transducer to measure the focal parameters of this unit. The image to the right is a graphical representation of the X- Y beam profile while the image to the bottom represents the X-Z beam profile measuring the focal depth. Numerical data is converted to acoustic pressure or intensity using a calibrated system. 6

7 Transducer Selection Transducer Model Types Depending upon the desired application, a certain transducer model may be more appropriate. The below table summarizes the general use for each main model currently produced by Ultran.
