Abstract:This paper introduces the system composition and structure characteristics of three kinds of air pressure verification devices in detail.The verification conclusions and measurement results of three kinds of air pressure verification devices are compared and analyzed.And the reasons for the difference are analyzed.The results show that the verification conclusions of the same PTB220 air pressure sensor are consistent with those of the three kinds of air pressure verification devices,but there are some deviations in the measurement results.And the comparison results can provide reference for inspectors.
