Abstract:

A promising new line mechanoelectrical transducer based on the electret phenomenon is considered for use as a variational pressure sensor in the underwater environment. Theoretical design considerations were developed for these coaxial cable devices with regard to sensitivity, geometry, frequency, input electronics type, and ambient pressure. Test results are reported comparing samples of one type of cable transducer to a calibrated hydrophone under two different test setups, for a variety of ambient pressures, and using two different types of excitation. In these tests, the cable tranducer is found to compare favorably with the standard hydrophone with respect to sensitivity and to immunity to value of ambient pressure up to 2500 psi. Author
