Stanford PPM100 Partial Pressure Monitor for RGA

The PPM is a stand-alone controller/monitor for Stanford's residual gas analysers. It measures partial pressures from Stanford's RGA's and total pressure from up to four capacitance manometers. Graphical output is available on a touchscreen LCD. The PPM100 includes 8-channel process control capability, four analog I/O ports, RS-232, USB and GPIB computer interfaces, and a web interface.

Features:

• Stand-alone RGA controller
• 8-channel process control
• Pressure vs time curves
• 4 analog input/output ports
• RS232, GPIB and USB interfaces
• Web enabled

Residual Gas Analysis
The PPM100 is designed to monitor and control a single Stanford RGA. A menu driven user-interface allows the operator to easily program RGA parameters from the front panel (ie, no host PC required). RGA data can be viewed as an analog scan, partial pressure vs time, leak trend (w/ 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.

Web Access
A built-in embedded web server connects the PPM100 to the web (password protected). The EWS can deliver measurment data to any standard internet browser. Use the EWS to monitor and control your vacuum system or to get automatic email notifications of potential or real system problems.
