Title: Welcome To Instrumentation Boot Camp 101


1
Welcome To Instrumentation Boot Camp 101
  • Your Commandant 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?

  • Notes and or comments will posted on my website

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
  • Act..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 networksmaintenance 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 orificeswater and or dirt will destroy it
    and or plug the lines

20
Pros and Cons
  • P motive force use I.e cylinderactuators
  • C lag time
  • Cleaks,signal losses
  • C Low gainprecision
  • 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
  • fiberoptichydrauliccat 5 duplineDevicenetProf
    ibusTCP/IP
  • wireless comm. Not yet proven.!

25
Questions ???
  • Not too hard please Im tired!!!

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