DEVELOPMENT OF A NEW PIEZOELECTRIC DYNAMIC PRESSURE GENERATOR FOR HIGH PRESSURE PERIODIC AND APERIODIC CALIBRATION
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-topeak 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.
