The NBS conical transducer: Analysis

摘要: The NBS conical transducer is a sensitive, broadband device for the measurement of surface displacement as function time. Its uses include acoustic‐emission testing. Here, operation this subjected to straightforward analysis. Although several approximations, some more dubious than others, are made, model predicts main features rather well. important parameters size and shape active element, source impedance (looking into area whose deflection being measured), terminating (back load).
