A Comparison of AE Sensor Calibration Methods

Popis výsledku v původním jazyce

The paper reviews the background of the primary calibration of acoustic emission (AE) sensors and the determination of uncertainty in the calibration. The main sources of uncertainty in practical usage of calibration results are discussed. The comparisonof the results of the reciprocity primary calibration, step-force and reciprocity calibration with broadband-pulse excitation method is presented. The shape of calibration characteristics corresponds well up to 300 kHz. The calculation of the uncertainty in all the calibration methods is described. The problem of propagation of uncertainty in the fast Fourier algorithm was solved. Uncertainty of measurement by primary calibration is determined and the influence of selected sources of uncertainty for each used method of calibration is presented and practically measured results are discussed. Piezoelectric AE sensor PAC UT1000 was used as the sensor under test. The big influence on uncertainty in calibrations was the influence of remount
