Abstract

The dynamic response of pressure sensors for model tests of sloshing impacts is paramount to recording these highly dynamic events. In this study, we investigated the dynamic behavior of the new pressure sensors presented at ISOPE 2018 (Schreier and Poelma, 2018), which increased the spatial resolution of sloshing pressure measurements by a factor of 5 compared to common sloshing pressure sensor arrangements. Wet drop tests were conducted and the resulting pressure signals were compared to theoretical results of the Wagner solution. For peak pressures over the full measurement range of the sensors, the rise time was found to be less than 0.25 ms, which was close to the theoretical minimum rise time of the generated pressures. Furthermore, the pressure sensors were found to have low sensitivity to accelerations. The results of this study indicated that these new pressure sensors were applicable for sloshing investigations.
