  1. Welcome To Instrumentation Boot Camp 101 • YourCommandant for the next 5 weeks: J.C.Labelle

  2. Industrial Controls &Process Automation • What is this all about? • Can I handle it? • Where Can I get Help?

  3. jc.labelle@videotron.ca514-916-5895Conval Quebec 514-332-2301 • Notes and or comments will posted on my website: • WWW.belletek.com

  4. Introduction: Process control and instrumentation companies= 2 Billion $ sales • 50,000 jobs in engineering,design as well as sales and technical support in North America

  5. Before we can head towards the storm…….

  6. Time to learn a Language!!

  7. Basics! ISA Symbology

  8. What it Really Means

  9. Even more to confuse you

  10. We need a dictionary!!

  11. Example:

  12. Loop types: • Open… no feedback to primary element • Closed: three compnents • S….ense • D….ecide • A…ct………..the output affects the input!!

  13. Signal Types

  14. Is it break time yet????

  15. Air Signals • Started turn of the century 0-60 psi • Next came 3-27 psi • Bailey Controls did 6-30 psi • Now standardized at 3-15 psig.

  16. Air Is cheap!!! Or is it? • Filtered to 25 micron or better for instrument grade • dryness to -40 F dewpoint • capacities!

  17. Costs: • 3-4 times more expensive than electronic instruments • expensive networks;maintenance issues • primary uses are for pneumatic operated actuation and explosion proof areas • Almost impossible to buy pneumatic temperature or flow or pressure transmitters

  18. Pneumatic Relay:

  19. Did you get all that??? • Just remember pneumatics have 3 thousanths of an inch orifices…water and or dirt will destroy it and or plug the lines

  20. Pros and Cons: • P: motive force use I.e: cylinder;actuators • C: lag time • C:leaks,signal losses • C: Low gain;precision • C: Expensive to produce

  21. Electrical Signals: Voltage or current? How far? Precision? Cost of installation Maintnenace issues

  22. Electrical Signals • Voltage used in HVAC =0-10V/1-5v/0-1ma • short distances no problem 50 -100 ft • voltage picks up sorrounding noise • cheap to produce • little maintneance

  23. Electrical Signals • Current signals..10-50MA/0-20madc/0-1ma • 4-20ma is the standard • 1 kilometre ranges • shielded cables (instrument side to ground) other end floats.

  24. Electrical Signals • All instruments generally use 4-20madc • other signals: • fiberoptic;hydraulic;cat 5 ;dupline;Devicenet;Profibus;TCP/IP; • wireless comm. Not yet proven….!

  25. Questions??? Not too hard please …I’m tired!!!

  26. Homework! • Using what you know…. • 3 loop drawings temp/flow/level • identify the elements • SDA!! • CPPA show!!
