Abstract:
1. A system for monitoring mechanical waves from a moving machine which in operation has moving particulate matter therein, the system comprising at least one sensor located on an exterior surface of the moving machine at a location away from the central axis of the machine, the at least one sensor sensing acoustic waves and including a transmitter for transmitting electrical signals representing the sensed waves over a predetermined period of time to a receiver at a location remote from the at least one sensor, a data processor connected to the receiver receiving signals from the receiver which signals represent the sensed waves and receiving data relating to the position of at least one sensor as the at least one sensor moves with the exterior surface of the machine and processing the signals to produce output signals for display on a display means, wherein the output signals for display represent one or more parameters indicative of mechanical waves emitted from the moving machine over a predetermined period of time.
