Overview
Overview
The 307501-B0A-T1 Vacuum Gauge Controller is configured for Series 274 glass tubulated or nude (not UHV) Bayard-Alpert gauges with resistive degas and comes with a half rack mount and remote power supply. It displays Torr measurement units, and is powered by 120 VAC with a US power cord. A RS-485 interface card in Slot X allows for pressure data output and set point status and provides remote ON/OFF control. Two set point relays 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.
