The 307507-C10-T3 Vacuum Gauge Controller is configured for Series 274 UHV nude Bayard-Alpert gauges with electron bombardment degas and comes with a left mount controller, side-by-side with power supply for 19-inch rack. It displays Torr measurement units, and is powered by 220 VAC with a EU power cord. A IEEE-488 interface card in Slot X allows for pressure data output and set point status and provides remote ON/OFF control. A Dual Convectron Board in Slot Y operates two Granville-Phillips® 275 gauge tubes allowing for automatic turn-on of the ionization gauges at pre-selected pressure. Series 307 controllers measure pressure, and utilizes pressure related outputs to control a variety of vacuum system functions and processes.
