Establishment of High Static Pressure Differential Calibration Device and Evaluation of Measurement Uncertainty
Differential pressure test instruments are widely used in aviation and other fields,based on the field working conditions and other factors,the accuracy of the differential pressure instrumentation may change over time,in the high static pressure detection of poor static pressure performance of the results of the differential pressure transmitter will produce a large error,if not carried out in advance of the high static pressure static pressure differential pressure detection of the differential pressure transmitter,the credibility of the verification will exist in a series of questions.The This paper introduces the characteristics of the high static pressure differential pressure calibration device,and through the benchmark level measurement standards to analyse the device measurement uncertainty,for the aviation engine test data accurate and reliable to provide strong technical support.
