NDT and Characterization of Low Gauge Pressure Gas Sensors

This paper presents the test system and methodology for NDT and characterization of gas pressure sensors in the gauge pressure range of 0, 015 bar to 2 bar developed in Laboratory for Process Measurement (LPM) at Faculty of Mechanical Engineering and Naval Architecture (FSB) in Zagreb. The design of the system, theoretical basics, main parameters influencing the test pressure and the model for estimation of measurement uncertainty is described. The test pressure loading strategy is discussed having in mind the desired characterization data. The model for evaluation of basic short term static characteristics of the sensor is described. The scope of the test system and methodology is presented through detailed example evaluation of pressure sensor with results presented in graphical and tabular form.
