Abstract − The need for dynamic pressure calibration has been increasing in the past years. Many solutions have been developed to satisfy this demand; nevertheless both present periodic and aperiodic systems do not cover the whole range of needs, calling for further development effort. In this contribution is presented a newly designed piezoelectric-actuated dynamic high-pressure calibration system that operates both periodically, 70×105 Pa peak-to-peak at 300 Hz, and aperiodically, almost 50×108 Pa/s. Concept, design and first experimental results are described. First encouraging results foster further enhancement of performances.
