| Abstract: | A new sweeping frequency absolute pressure calibration system for dynamic pressure calibration of under atmosphere is described.This system can generate not only sine absolute pressure wave,but also sweeping frequency absolute pressure wave.It can be used to calibrate the amplitude and phase of absolute pressure sensor at giving frequency or at giving frequency range.The working frequency range of this system is(1～5000)Hz,and working pressure range is(1～200)kPa. |
