Morgan Advanced Materials, a world leader in advanced materials for the electronics, energy, healthcare, petrochemical, and transportation industries, has announced its capability to design and manufacture a range of components that are compatible with ultrasonic Acoustic Doppler Current Profilers (ADCP) technologies. In addition to offering advanced ADCP materials, Morgan also manufactures braze alloys, high temperature insulation, molten metal systems, seals, bearings, and more.
The ADCP is a hydro-acoustic current meter which resembles sonar. This technology is able to measure water current velocities over a depth range by utilizing the Doppler Effect where sound waves are reflected back from particles within a water column. This innovative technology can be used in many applications, including oceanographic surveys, waterway, and wastewater usage.
ADCPs have been on the market for many years, but new developments have greatly improved the efficiency and versatility of this technology. Today, working frequencies start at 38 kHz and increase to several megahertz, depending on what kind of ADCP you choose.
To further enhance its ADCP, Morgan Advanced Materials is creating ceramic ultrasound transducers that come in a wide range of shapes and geometries measuring up to 10 inches in diameter. It is also harnessing its manufacturing capabilities in order to produce large ceramic blocks that are perfect for low frequency requirements. The transducers use piezo-composite elements in order to increase efficiency, bandwidth, and range.
Made from a modified range of soft piezoelectric (PZT) materials, including PZT5H1 and PZT5A1, the transducers have been specially developed. Using inspiration from Morgan’s proprietary range of ceramics, the new products are able to deliver greater sensitivity. The transducers utilize large size blocks, which increase directivity, lower the operating frequency, and reduce the profiling range, all while accounting for interference from objects that are located within the profiling range.
