Abstract
A detector arrangement, for selective detection of vibrations on a component, comprises a film fitted with at least one piezoelectric element. The film is attached to the component in such a way that occurring mechanical vibrations act on the piezoelectric element, such that an electrical charge with a frequency correlating with the mechanical vibration is generated at the connection electrodes of the piezoelectric element. An electrical filter is connected to the piezoelectric element and filters out the component of the supplied charge which corresponds to a predefined frequency. An electrical charge storage means which is connected to the filter is used to accumulate the filtered-out charge components. A signaling means is also provided, which generates an electrical signal as soon as a predetermined charge limit value is reached on the charge storage means.
