307 Bayard-Alpert Vacuum Gauge Controller
Model: 307507-D1B-T1
Overview
Overview
The 307507-D1B-T1 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 120 VAC with a US power cord. An linear analog output card is included in Slot X. 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. Six set point relays (2 per channel) for ion gauge are included. Series 307 controllers measure pressure, and utilizes pressure related outputs to control a variety of vacuum system functions and processes.
