Download or read book ELECTROACOUSTIC TRANSDUCERS FOR A 10 000 psig UNDERWATER SOUND TRANSDUCER CALIBRATION FACILITY FOR THE FREQUENCY RANGE 10 TO 4000 Hz written by Ivor D Groves (Jr) and published by . This book was released on 1969 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and construction of the terminal and source transducers, a reciprocal spherical piezoelectric ceramic transducer, and the probe hydrophones that are part of a new USRD measuring facility are described. The facility is used for the calibration of underwater sound transducers in the frequency range 10 to 4000 Hz at hydrostatic pressure to 10,000 psig and controlled temperature from 3 to 45 deg C. It operates on the principle of active-impedance termination in a rigid-walled, water-filled tube.

This book was released on 1969 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electronic instrumentation of a new measuring facility for calibrating underwater sound transducers at controlled temperature from 3 to 45C in the frequency range 10 to 4000 Hz at hydrostatic pressure to 10,000 psig is described. The pressure vessel consists of a vertically mounted 20.3-cm-i.d. stainless-steel tube 274.3 cm long. An active-impedance termination can be established at one or both ends of the tube to provide a plane, progressive wave within it. Three phase- and amplitude-adjustable outputs from the signal source activate the source transducer and those that control the terminal impedance. Multiple probe transducers and receiving channels serve to establish and monitor the required wave condition. Delay lines enable rapid and convenient adjustment to obtain minimum standing-wave ratio.

This book was released on 1969 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new controlled-environment facility operating on the principle of active-impedance termination in a rigid-walled tube now provides the means of calibrating a wide variety of underwater sound transducers in the increasingly important frequency range 10 to 4000 Hz at static pressure to 10,000 psig and temperature from 3 to 45C. This report describes the theory, limitations, and mechanical features of the facility and presents examples of both primary and secondary calibrations of transducers in the tube and in a free field.
