ultrasonic transducer

[¦əl·trə′sän·ik tranz′dü·sər]
(engineering acoustics)
A transducer that converts alternating-current energy above 20 kilohertz to mechanical vibrations of the same frequency; it is generally either magnetostrictive or piezoelectric.

Determine the applicable ultrasonic transducer frequencies, coupling methods, configurations, and placements for wave speed monitoring and web defect detection within an extrusion process;
The ultrasonic probe was composed of a steel clad buffer rod and a 5 or 10 MHz longitudinal piezoelectric ultrasonic transducer (UT) attached to the transducer end of the buffer rod (10, 12).
The ultrasonic transducer operates at a fixed frequency and produces vibrations with maximum amplitude at the tip of the spray forming head.
The identification of defects in the shrouded area through the use of beam spread is critical because this portion of the pin is not directly visible to the straight-beam ultrasonic transducer.
Following RCNDE research undertaken at Strathclyde University, an innaccessible vessel in the Magnox Reprocessing Plant at Sellafield was inspected remotely by a robot carrying an ultrasonic transducer. This allowed measurement of the actual wall thickness rather than using corrosion modelling to make an estimate.
The 87 papers discuss such topics as the finite analysis of cutting temperatures with an internal lubricating tool, abrasive-assisted electroforming of nickel on a translational cathode, analyzing the stability of the Hebei Hongfeng Wind Farm integration, simulating the acoustic field of a spherical shell focused ultrasonic transducer, the diagnosis of engineering mechanical faults based on the Internet of Things, and experimental research on the relationship between surface polishing and fracture strength for ground ceramics.
GE Measurement & Control has said its new T17 ultrasonic transducer provides accurate measurement of gas flow down to 0.1 f/s (0.03m/s) rates and is ideally suited to measuring low flare gas flows when used with GE's GF868 or XGF868i digital flowmetering systems.
