The Sentinel Vacuum Controller helps maintain a stable and consistent vacuum essential to proper functioning of a milking system. A vacuum controller or regulator is used in many types of vacuum systems to set and control vacuum at a desired level. The objective of a vacuum controller is to maintain a constant vacuum regardless of the flow in the system. The Sentinel Vacuum Controller is a diaphragm-operated pneumatic valve. The Sentinel is not load sensitive to normal CFM usage. This means, that as changes take place in the system, the Sentinel will automatically compensate for the changing load. The Sentinel has a fully-open to fully-closed span of .2" mercury Hg. This means that when the vacuum rises or falls more than .2" mercury Hg, the controller will open to maximum or it will close.
Use Sentinel as your primary vacuum controller to maintain the most stable & consistent vacuum in your vacuum system. The Sentinel has set the highest standard of vacuum control for over 36 years. Use Sentinel with existing Variable Frequency Drive systems to provide 1) security; 2) a stand-by or secondary vacuum controller; 3) control for wash-up; 4) a secondary relief valve. The Best Way to Control Vacuum on a Dairy Farm |
A dairy operation can substantially improve its vacuum system efficiencies by doing the following: Proper and periodic maintenance of the vacuum controller Proper sizing of the vacuum pump within the system Proper placement of the vacuum controller in the system
Many users of various types of vacuum systems have specifically switched to our controllers to obtain better vacuum control. Our Sentinel line of Vacuum Controllers, which have been designed for dairy farm use, have also been used successfully in: pneumatic conveying systems, vacuum hold-down, pick and place, mail distribution systems, whey production, poultry systems, laminate systems, printing systems, various systems using a pressure controller, soil vapor extraction, manure handling systems, cheese processing, central vacuum systems, router systems, dental systems and woodworking systems. Allows a pre-set vacuum level to be maintained with + or - .2" mercury Hg over an adjustable range of 10"-15" mercury Hg gauge pressure at the controller. Sensitive to .1" mercury Hg of vacuum change. Responds to vacuum change in milliseconds. Four models to accommodate different system requirements. American Made
