The Series 307 Vacuum Gauge Controller (VGC) measures pressure, and utilizes pressure-related outputs to control a variety of vacuum system functions and processes. To fit a wide range of needs and applications, the 307 VGC is available in a variety of configurations and prices. In its simplest form the 307 VGC runs a single ionization gauge (IG) in the range from 1 x 10-10 to 1 x 10-1 Torr. With available modules, the 307 controls four gauges, measuring pressure from 2 x 10-11 Torr to atmosphere, and six process control setpoints.
Unique design improvements have resulted in:
Capable of pressure measurement at up to four locations in your system or process using two ionization gauges sequentially and either two Convectron Gauges or two thermocouple gauges or one Convectron plus one capacitance manometer simultaneously.
Excellent system control: Up to six process control set points are available and can be enabled automatically at pre-selected pressures or manually.
Increased reliability: dramatically decreased probability of component failure due to conservative design and cooler operating temperature achieved by removing the separately packaged power supply to a remote location. This time proven design is backed by Brooks’ five-year limited warranty.
Greater safety: electric shock danger significantly reduced by using only low voltage circuits in the control unit.
Improved economy: modular design enables users to purchase only required capabilities, and allows for easy upgradability in the future.
Panel space savings: only half the conventional rack width is occupied by the 307 control unit. Since no ventilation is required, space above and below the control unit can be used more efficiently.
