PPM100 — Stand-alone monitor for RGA - 1

PPM100 Partial Pressure Monitor • Stand-alone RGA controller • 8-channel process control • Pressure vs. time curves • 4 analog input/output ports • RS-232, GPIB, Ethernet and USB easily program RGA parameters from the front panel (i.e., no host PC is required). RGA data can be viewed as an analog scan, partial pressure vs. time, leak trend (with audio signal), or single mass readings. This data can also be linked to alarms, process control relays, and analog ports for closed-loop control of specific component gases. Analog I/O The PPM100 has four configurable analog I/O ports. These can be used as outputs to control auxiliary vacuum equipment such as heaters, actuators, ion sources, programmable logic controllers, and throttle controllers. As inputs, up to four capacitance manometers can be monitored simultaneously. The PPM100 is a stand-alone controller/monitor for SRS residual gas analyzers. It measures partial pressures from SRS RGAs and total pressure from up to four capacitance manometers. Graphical output is available on a touchscreen LCD display. The PPM100 includes 8-channel process control capability, four analog I/O ports, RS-232, USB and GPIB computer interfaces, and a web interface. Residual Gas Analysis The PPM100 is designed to monitor and control a single SRS RGA. A menu driven user-interface allows the operator to Monitor mode SRS Stanford Research Systems phone: (408)744-9040 www.thinkSRS.com
