Spherical Ultrasonic Piezo Transducers from PI

Piezoelectric ceramic transducers are well-suited for industrial, medical applications, and scientific applications that require frequencies above 20 kHz.

As a leader in piezo transducers, piezo mechanisms, and precision motion control solutions, PI (Physik Instrumente) offers a line of standard and custom electro-ceramic hemispheres and hollow spheres for applications from echolocation (sonar) to flow measurement. As a global leader in piezo actuators and sensors, these new components join the existing extensive catalog of disk, rods, cylinders, plates, blocks, rings, and tubes employed by high-tech research and industry fields, including medical engineering, mechanical engineering, aerospace, and semi-conductor applications.

Inverse Piezo Effect Applications
Piezo ceramics convert electrical power into mechanical power and vice versa; the inverse piezo effect is harnessed for its fast, precise motion and oscillation generation. For ultrasonic applications that require high bandwidth, hemispheres and hollow spheres are currently available with an outside diameter range from 10 – 60mm and 1mm wall thickness. Uses for electro-ceramic transducers range from the necessary and mundane to out-of-this-world scientific advancement: removing dental plaque, ultrasonic imaging, monitoring flow measurement or fill levels, preparing soil samples on Mars for spectroscopy.
