measurement microphone / piezoelectric / pressure

High sensitivity dynamic pressure transducers are suited for applications in high intensity acoustic, turbulence, and cavitation measurements. It can be superimposed upon high static pressure fluid media. Axial pressure applied via a diaphragm to electrical charge is converted by the sensing element. Response to static loading comprises generation of an initial condition charge followed by exponentiation to zero at a rate determined by instrumentation properties and leakage.Thus a pressure field comprising both static and dynamic components will convert to dynamic charge only, with the static element transparent. . The charge sensitivity is the slope of the charge vs. pressure characteristic of the transducer, (?q/?p)/P up to its safe static pressure limit, and will be invariant for Q vs. P linear.
