Vacuum Regulator - Model 450
DigiVac has an Innovative vacuum level controller with proportional valve and isolated transducer available with absolute or differential control options. The DIGIVAC model 450 is a self contained vacuum level control unit for maintaining pressures between 1 and 760 Torr. It provides dependable digital control of your vacuum system with a innovative controller technology to make testing easier. The 450 has a gas independent isolated stainless steel sensor and optional stainless steel piping to enable implementation in the most corrosive environments. The heart of the unit is a proportional valve that allows the controller to make precise changes in vacuum flow to achieve a very stable vacuum level. The unit also adds a bleed valve so level control can be achieved from using both the vacuum and the ambient pressure. The 450 has full manual control available via a dial on the front panel, or can be controlled remotely via RS232. The DigiVac VDS software is also available which enables the user via a PC to run a recipe of 16 time duration and vacuum levels. The display is an easy to read back lit LCD display with an intuitive readout of both the current vacuum level set point, current vacuum level, valve duty cycle and mode. The 450 has been tested in both house vacuum and directly connected vacuum pump configuration to maintain both an absolute and differential vacuum level. This vacuum controller is in use for altitude simulation, pharmaceutical research and in manufacturing industries to control the vacuum level in evaporator flasks and vacuum vessels.
