A controller for monitoring and controlling an operating pulsator in a
milking system is shown. The controller comprises a first sensor
operatively connected to a designated pulsator for receiving a pulsating
vacuum therefrom. The controller produces a first signal representing the
pulsating vacuum level. A processor is operatively connected to the first
sensor for receiving the first signal. The processor includes a
comparator for comparing the first signal to a stored reference signal
representing a predetermined vacuum range of pulsating vacuum levels
programmed as acceptable for milking system pulsators. The processor
generates at least one control signal when the designed pulsator
pulsating vacuum level is at a vacuum level outside of the predetermined
vacuum range. A control circuit signals that the designated pulsator
pulsating vacuum level is outside of the range of pulsating vacuum levels
programmed as acceptable for the milking system pulsators.
