Knowledge of time-resolved pressures, densities of spray and spall is required for the full understanding of ejecta production. One method of studying spray and spall is through the use of piezoelectric probes. A widely-used piezoelectric probe is manufactured by Dynasen Inc. The probes performance in a range of environments will be discussed, including gas-gun generated sprays. Spray densities obtained via X-ray imaging and high-speed photography are compared with the probe density measurements to give an indication of how well the probes perform. Various probe shielding arrangements are discussed, and the importance of impedance mismatches between the impacting material and the PZT is highlighted.
