| Abstract: | The Security monitoring system’s field pressure parameter measurement system is established based on the field pressure measurement of pressure transmitter，signal conversion and transmission,and pressure terminal display.The on-line calibration method of security monitoring system’s pressure parameters is introduced.The mathematical model of measurement error is established.The source of uncertainty of the system’s pressure measurement results is analyzed.The main contribution components of the uncertainty of the field system calibration measurement results are given by the experimental verification analysis. |
