ABSTRACT:
An apparatus for predicting a fault condition for a machine is disclosed. The machine has a plurality of parameters being dependent upon machine performance. A sensor connected to the machine produces an electrical signal in response to one of the plurality of machine parameters. A computer produces a data trend of the parameter in response to the electrical signal, calculates the duration and slope of the trend, and predicts the time period in which the trend will exceed the warning level.
