Abstract

There is provided an apparatus and method for monitoring pulsation of a milking system in a dairy facility. The milking system includes vacuum hoses that extend from a vacuum source to a milking claw. The pressure in each vacuum hose is changed by a pulsator, with the vacuum hoses being out of phase with one another. The pressure sensors are coupled to the respective vacuum hoses, which sensors monitor the pressure pulsations to ensure that the pulsator is operating satisfactorily. The pressure sensors are coupled to the vacuum hoses by way of passageways or hoses. A bypass is provided between the passageways so as to provide air circulation in the otherwise dead air space in these passageways. The bypass is small so as to not interfere with the pressure measurements by the sensors and is located in close proximity to the pressure sensors so as to minimize the amount of dead air space. The bypass is operated continuously as long as the milking system is operated in order to prevent the accumulation of moisture and debris in the space between the bypass and the pressure sensors. The bypass enhances the reliability of a continuously operating pulsation monitoring apparatus.
