Abstract
A method for detecting faults or defects in moving machine parts wherein mechanical vibrations produced by a fault or defect are converted into an electrical signal from which the condition of the machine part is obtained. For converting the mechanical vibrations into an electrical signal, an acoustic-emission transducer with wide bandwidth is used. A frequency range in the electrical signal is selected where the half wavelength is smaller than the smallest linear dimension of the cross section of the transducer face which is in contact with the machine part.
