^4fDynamic Pressure Calibration at CIMM

摘要

^7fDynamic pressure measurement is widely used in nowadays. To guarantee the measurement accuracy of dynamic pressure, Changcheng Institute of Metrology & Measurement (CIMM) is engaged on research of dynamic pressure calibration technology for over twenty years. Different kinds of dynamic pressure calibration devices that generate several types of calibration stimulation signal and cover the pressure range of 0-1000MPa and the frequency range of 0-10.000Hz are developed. In this paper the dynamic pressure calibration devices and calibration methods used in CIMM are introduced.
