RESEARCH METHODOLOGY FOR ESTIMATING THE AMPLITUDE-FREQUENCY CHARACTERISTICS OF PIEZOELECTRIC SENSORS BY USING A MECHANICAL SOURCE OF CONTINUOUS NOISE

Experimental results of amplitude-frequency response for acoustic emission sensors are obtained by using a mechanical source of continuous noise. The amplitude-frequency characteristics of a calibrated transducer are analyzed during the registration of longitudinal, surface and Lamb waves. Experimental characteristics of different-type bandpass sensors installed on the object are discussed.

Keywords: Acoustic emission test, acoustic emission sensors, calibration, amplitude-frequency characteristic, sensibility
