Abstract:
1. A controller for monitoring and controlling an operating pulsator in a milking system, said controller comprising a first sensor configured to be operatively connected to a designated pulsator operating in a milking system for receiving a pulsating vacuum therefrom and for producing a first signal representing a pulsating vacuum level received from the designated pulsator; a processor operatively connected to said first sensor for receiving said first signal representing said pulsating vacuum level from the designated pulsator, said processor including a comparator for comparing said first signal to a stored reference signal representing a predetermined vacuum range of pulsating vacuum levels programmed in the form of data/instructions from a computer and wherein said programmed vacuum levels can be changed by computer programming and such programmed vacuum levels are the pulsating vacuum levels acceptable for milking system pulsators, said processor generating at least one control signal when the designed pulsator pulsating vacuum level is at a vacuum level outside of the predetermined vacuum range; and a control circuit responsive to said at least one control signal for signaling that the designated pulsator pulsating vacuum level is outside of the range of pulsating vacuum levels programmed as acceptable for the milking system pulsators.
