    Abstract:

    In the field of dynamic pressure measurement, the pressure measurement system with transmission pipe is often used for the pressure measurement in narrow space and bad working conditions. The pressure signal through transmission pipe was often distorted, which becomes an important factor to decrease the frequency response of pressure measurement system. In this paper, the physical structure model of pressure measurement system with transmission pipe is introduced, and the dynamic measurement mechanism affected by the dynamic characteristics of transmission pipe is explained at first. Secondly, the calibration devices of transmission pipe and methods are introduced, a new calibration device and method is studied, and a static pressure and temperature adjustable calibration device is developed. Finally, the calibration device is used to test the pressure measurement system with transmission pipe, which can be used as a reference to the development of dynamic measurement and compensation technology of pressure measurement system with transmission pipe.
