Abstract
Sloshing impacts are highly dynamic and localized events. One problem in the measurement of sloshing impact pressures is the limited spatial resolution that can be achieved with current sensors. To overcome this hurdle a project was started to develop new sensors that allow to increase the spatial resolution of pressure measurements by a factor 5 compared to current test setups in sloshing experiments. The sensors were based on commercially available MEMS devices, which are suitable for measurements with liquid media. The main application of these devices are static pressure measurements. Therefore a qualification program for the new sensors for sloshing applications was started. First static and dynamic measurements in air gave promising results and encourage to continue this development with future tests in water.
