Static pressure and temperature adjustable sinusoidal pressure loading device

Abstract

In this paper, a sinusoidal pressure loading device based on static pressure and temperature is introduced for the use of dynamic calibration and testing of the pressure measurement system with transmission pipe. The device can generate a sinusoidal pressure from 1 kPa to 10 kPa under the static pressure no more than 1 MPa and frequency within (20–1000) Hz, meanwhile dynamic sinusoidal pressure loading can be carried out within (20–400) °C. And then the dynamic calibration of transmission tube under actual conditions can be simulated.
