Evaluation of the AN/SQS-23 TR-208A Transducer (Serial BTD-2-69).
Abstract
ARL evaluated the AN/SQS-23 TR-208A transducer (serial BTD-2-69) by measurements at the Lake Travis Test Station in April 1969 and by shipboard measurements in September 1969. The principal measurements made were complex impedance (Z and 0) of individual transducer elements, driven individually at operating power. A conclusion drawn from this work is that impedance data measured on the bare transducer in open water compare (to within measurement accuracy) with the shipboard measurements made in the dome. This is a highly favorable indication and is a further incentive for the widespread use of element impedance measurements for transducer evaluation. In the past, such measurements have proved to be very effective at diagnosing transducer failures and impending failures. (Author)
