what are our objectives when we design an analyser system
What are our objectives when we design an analyser system?
  • Get a sample out of the process and into contact with an analyser
  • Make a measurement and check that the result is valid
  • Send the result to the DCS
  • Facilitate maintenance
what constraints are we designing to
What constraints are we designing to?
  • Cost of build
  • Cost ownership
  • Value added
pipeline to pixel objectives for today
Pipeline to Pixel: objectives for today
  • How to design a NeSSI sample system?
  • How to connect up the measurement domain?
  • How to get data through to the DCS?
  • How to maintain the system?
using the doe schematic as an example
Using the DoE schematic as an example
  • Look at the design of the sample system
    • Celerity, CIRCOR, Parker, Swagelok
  • Select transducers and components
    • CPAC web-tool
  • Review SAM and the measurement domain
    • Honeywell
  • Learn about OPC as a connectivity mechanism
    • Matricon
  • Consider how to make maintenance easy
    • Antelope
the doe schematic
The DOE schematic
  • 2 process streams, zero and span
  • Liquid or vapour process samples
  • GC or other analysers
  • Quite a few sample controllers and sensors
  • Hazardous area
  • Heaters for substrate and enclosure
