<p>A passive acoustics system is described for monitoring the operation of a fluidized bed in a fluidized bed system. The passive acoustics system employs vibrational analysis technology which translates acoustic/vibratory energy created by industrial processes into useful, process-related information. The passive acoustics system comprises a sensor for transforming vibratory energy of a container containing a fluidized bed into electrical energy, an amplifier, a data collector for converting electrical signals from the amplifier from a function of time to a function of frequency, a computer, and means to transfer electrical signals from the data collector to the computer wherein the signals are algorithmically converted to process-related information.</p> |
