I picked up 5 Beckman Industrial Series 7200 temperature controllers
on ebay a while a go for $10


Best as I can figure out..these are capable of ramp up, hold, ramp
down etc etc all programmable with plenty of relay outputs etc

Only problem is..no manuals to be found.

My Google Fu has been defeated. I think Beckman Industrial was sold
to Emerson Electric, but calls to the various Emerson, Beckman,
Beckman Coulter etc etc are all resulting in pretty much a universal
"Huh?"

Model Number DC7212

I put 110vac on one, powers up fine, a type K platinum thermocouple on
the Sensor input..and it displays air temperature..(currently at
9pm...93F with the fans in the shop running)

I can go into the Menu..but none of the entries mean anything without
documentation

Anyone got a clue as to where to call next?

I figure these would control heat treating ovens very very well as the
one mention I could find on the internet was using it to control
heaters in a physics experiment

It does ramp up/down, time etc etc

Hi Gunner.
Lots of this stuff recently is private-labelled, could be the case with your
units.
Maybe post a link to a photo, and see if someone here can recognize it by
appearance.

It's possible Wavetek bought up that line of products. I have no idea who
has the Wavetek line of small instruments like meters now though, but it
has changed hands yet again.

Hi Gunner.

You may also want to post your question on sci.engr.control. It's got
less than 1% of the traffic of this group, but there are a lot of
lurkers who use industrial controllers. Someone may have a line on what
you're looking for, particularly if you can toss a photo up on the web
someplace.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

My guess is this stuff is REALLY old, like 1970's. Orange
segment glow displays? Beckman made a lot of process
instruments to sell their "nixie" tube line.

If it is newer than that, maybe with a vacuum fluorescent
display (blue), it may be the same as an Omega controller from
the same vintage. You can probably get lucky and find an old
Omega catalog that may JUST have enough info to gewt you going.
They printed them by the tons and sent them out with the EE
master catalogs.

Not Nixie...LED

The 'styling" says late 80s mid 90s to me. Shrug

http://www.big-list.com/usedmanu.html sometimes helps you track down a
manual.

There are two kinds of people on this earth:
The crazy, and the insane.
The first sign of insanity is denying that you're crazy.

I don't know how familiar you are with that generation of controller,
but after working with a lot of different makes & models, I've noticed
similarities in the set up procedures. The real bitch is if you have
to do voodoo to move to different programming levels in the menus.
Other than that, a familiarity with the general programming structure
will help a lot.

Persistance in a search also may pay off. Perhaps you could find a
large rep for that stuff who may still have a copy of the manual. I've
done that before.

Good luck

Doric Instruments bought Beckman's line of controllers.

HaHa, it looks like their products haven't been changed in decades so
getting a manual should be easy.

"I am for doing good to the poor, but I differ in opinion of the
means. I think the best way of doing good to the poor, is not
making them easy in poverty, but leading or driving them out of
it. In my youth I travelled much, and I observed in different
countries, that the more public provisions were made for the
poor the less they provided for themselves, and of course became
poorer. And, on the contrary, the less was done for them, the
more they did for themselves, and became richer." -- Benjamin
Franklin, /The Encouragement of Idleness/, 1766
