Evaluation of the uncertainty of measurement for a dynamic calibration approach for pressure sensors
Thomas Platte · Measurement Sensors · 2021
Pressure sensors are frequently used for dynamic pressure measurements but are mostly calibrated by static methods. This is done due to the insufficient availability of dynamic calibration methods. One approach to overcome this lack is shown in this paper. The developed calibration device is a pistonphone based exciter to calibrate the frequency response of common pressure sensors. The first section disuses the principle of operation of the exciter. The following chapters show the evaluation of the uncertainty of measurement. First all effects are named while few effects are highlighted in detail. The paper closes with the final outcome of the uncertainty of measurement.
