Abstract (en)
[origin: EP2732748A1] This present invention relates to a method and system of monitoring a pump (1) in a warewash maschine. The sensing system is capable of monitoring signals from mechanical liquid pumps used on a warewash machine. The sensed phenomenon may be directly related to the mechanical vibration of the pump. The signals obtained through such monitoring are processed in a manner that allows some major failure modes of a pump to be detected prior to complete failure of the pump so that the pump can be replaced at a convenient time prior to an unplanned loss of use of the warewash machine.
