80 kHz Cylindrical Ultrasound Transducer Omni-directional Horizontal Beam Directivity Broad Bandwidth Low Resonance Q Excellent Impact Resistance Lightweight Low Cost Piezoelectric Film (PVDF) 80 kHz Ultrasound Transducers offer unique advantages for air ranging applications. Cylindrical 80kHz PVDF transducers exhibit omni-directional horizontal beam directivity and broad bandwidth characteristics. These characteristics lend unique solutions in many applications such as two- dimensional positioning, digitizer, object detection, and distance measurement. Depending on the applications, resonance frequency and vertical beam directivity of the transmitter can easily be customized by changing the diameter and length of the PVDF cylinder. PVDF ultrasound transducers also have very low resonance Q values. Typically, PVDF transmitters have a Q value of 5. This means that the signal rise and decay times are much shorter than conventional ceramic ultrasound transducers. This characteristic is ideal for positioning applications.
