Abstract
A system for monitoring the operation of vibrating equipment, such as a vibrating screen unit or vibrating feeder. The vibrating equipment includes a series of mounting springs that support the body on a stationary support structure. The system includes a plurality of sensors that are positioned to detect vibrating forces on one or more of the mounting springs. Each of the sensors generates a monitoring signal that is received by a control unit. The monitoring signals are a measure of the resonance frequency of the mounting springs. The control unit is operable to compare the monitoring signals from the sensors to expected, normal values such that the control unit is able to determine whether the mounting springs are functioning in a normal manner or whether a problem exists. The control unit is further able to monitor the operation of the vibrating equipment through the analysis of the monitoring signals.
