Abstract (en)
[origin: WO9916538A1] The present invention includes a device for locating defective filter elements among a plurality of filter elements. The device includes a sound monitoring apparatus and a processing circuit. The sound monitoring apparatus is associated with a plurality of filter elements to detect sounds emanating from the plurality of filter elements and produce output signals indicative of the sounds. The processing circuit is coupled to the sound monitoring apparatus to determine the location of defective filter elements among the plurality of filter elements based on the output signals. The present invention also includes a probe for locating defective filter elements based on sounds emanating from the filter elements.
