Data Calculation and Analysis of Static Pressure Sensors
This article delves into the concept and performance parameters of static pressure sensors.Firstly,it outlines the inspection process according to the"Verification Regulation of Pressure Sensors(Static)JJG860-2015,"focusing on inspection instruments,zero offset detection,and output measurements.Secondly,it provides an in-depth discussion on how to computationally derive the working curve of a pressure sensor,encompassing the establishment of a calibration curve and the subsequent determination of the working curve.Lastly,it presents comprehensive steps for calculating various performance metrics of the sensor,such as sensitivity,repeatability,hysteresis,linearity,basic error,and long-term stability.By consolidating these technical indicators and analyzing the data methods mentioned in the regulation through quantitative calculations,the paper effectively enhances the metrological efficiency of static pressure sensors.
