Doug,

I'm an old Petroleum Worker. 60V is to capable of creating a spark hot
enough to Blow the Place up.


Yes, but these systems are (were) used in other potentially
flammable environments.


We did, however, use 25 Volt, 5 to 25 ma Instrumentation on the New
Refinery out here.


Yep been there done that too.

A Comment to satisfy ASA; I transfer out here because of my Pneumatic
Background, That is the reason for the name of my boat; "Pneuma" I had
to have an Air powered boat!! Also; Pneumatics have yet to create a
spark in an explosive environment.


Navy steam plant automation was pneumatic. That's what I
started on.

Our Instrumentation out here was basically "Rochester Analog" with
Fischer pneumatic driven control valves. Signals to "Big Blue" IBM
computer for accounting. It wasn't long before we upgraded to total
Digital, Followed rapidly to 100% Computer Control. However the same
old pneumatic valve are at the end of the control circuit.


Have you retrofitted optical position controllers on them?
They're the bee's knees, simple bulletproof and no
mechanical linkage. You can adjust the proportional band
from the control booth!

Autologging rocks. I am almost at the point where I can
simply phone in calibration from home... or from the boat!


My gang called me; "The Old Huff & Puffer" and I called them; "Wink,
Blinkers & Nodders" I called my Venture 2-22 "
"Huff & Puff"


I worked with a couple of guys nicknamed 'winken, blinken, &
nod' they liked to go hide in the plant & snooze. One of
them once get angry with me for not hunting him down &
waking him up when his shift was over.

Doug,

I'll be retired 22 years this July. What's taken place in
Instrumentation in that time is unbelievable. Before I left, we had the
operators dialing in PB changes, Range
changes and valve action changes
That was only the start. There is no way I could go back today.

Navy Systems; Were they Bailey or Haggen Systems? Most have been
abandon because of the Mercury. I loved those Bailey 3-system Bias
Panels. If I didn't get sick I could have made a very nice living just
teaching about them.
Them and the Haggen "Ring-balance" systems;----Ah but that was another
time. AND time to just let them live in memories

Hagan, although most plants had one or two Bailey components
(flow transmitters IIRC) in them.

Not sure what a "ring-balance" system is, the Hagan system I
know (and could still draw diagrams of) was made up of
little aluminum boxes with diaphrams pushing on a pivot arm.
Simple & flexible, the assembly of 4 chambers could be made
up different ways (springs, adjusting pivot point, feedback
needle valves) to get almost any control action. And it
would run OK with water & crud in the air lines.

Time certainly keeps rolling along.

Yup, but I finished 8th grade, first.

Yeah,

The Old Bailey transmitters removed the square root and produced a
uniform signal to simplify bias response. Now the Dp cell transmitters
remove the square root in the transmitted signal pneumatically or
electronically. No more mercury flow meters. To dangerous ?, so the
Safety People say. Boy were they accurate and stayed in Calibration for
years.

After I retired, I got roped into doing some ship conversions to
container ships. High Pressure Steam turbines. Not like the ones Scotty
was transporting.

In the Old Philadelphia Refinery. They used those steam engines for
pumps before they even had electricity. Some had Fly Wheels two stories
high. Each with its own building (Pump Sheds) They operated around the
clock. Three shifts. Usually with a Head Pumper and a couple operators
and helpers. They all had names; like "Big Mary", "Berty" and so forth.
The were cared for and pampered like you wouldn't believe. Custom paint
jobs and fancied up pump houses Things of Beauty they were.

Now gone and only a few of us old timers even remember.
