- Abstract:
- Up to now, there is no the international certified standard calibrator of dynamic pressure because the definition of dynamic pressure is not determined. Even though a few dynamic calibrators were designed, manufactured and used in a variety of industrial areas, they are not traceable to the international standards in practical. At present, the determination of response characteristics to pressure transducers is routinely limited to static calibration, while using a deadweight pressure standard. The deadweight device is a primary static pressure standard used to generate precise pressure under the assumption that the static and dynamic responses of the transducer in static calibration are equivalent. However, the differences in transducer response between static and dynamic events can lead to serious measurement errors. Dynamic techniques are required to calibrate pressure transducers to meet dynamic events in milliseconds In this paper, the calibration techniques are surveyed and classified in the area of dynamic pressure and finally analyzed in terms of the waveform, range, transition time and method of dynamic pressure so that its analysis result can be informative and helpful for those who are interested in dynamic pressure for better measurement.
