John, are you interested in trading for elements?

can this unit be used to control a small wire melter with a type s thermocouple?

Pete, I have to drive out to the studio today to get an element count before I answer that. I'll let you know via PM.

Mark, from the data sheet online I believe that it can: http://www.digitry.com/gb1.html
You would need to contact Digitry to be be certain, and to be clear - this unit has a type K thermocouple. It was used on an annealer.

I know the gb4 requires a different sending unit for an r or s thermoucouple. I run my furnace on one.

Thank you John that information helped. seems that buying a sending unit for an s type thermocouple would make this work. If the swap between Pete and yourself does not happen please let me know as I will be interested. I have contacted Digitry for clarification on if the external sender for an S type can be added as a "plug and play" or if it requires internal rewiring I will be in touch as soon as they are.

I have no vested interest in the controller. I have lots of stuff.

looks like the GB1 would have to go back to the factory for rewiring for use with an S type so I have to back out at this time.

I can't say enough good things about digitry. As I said I run my gas powered furnace on a GB5 and can't be happier. It's so easy to program. My partlow mic 6000 drove me INSANE.

The cost to have a gb1 re tooled to 5-20 milliamp output and a new sending unit is well with the money.

Pete, I'm finally going to get the time to drive out to the studio and get a count on the elements that I have left tomorrow. I'll let you know as soon as I do.

Fine. I'll give you an attractive price if I don't have to ship and I can always hold onto your elements . I need refreshing as to what they were. I no longer ship from here but I still have lots of them.

The thing I don't like about the Digitry is it has no "fuzzy logic". So it is always over and under shooting the temp. You can buy a controller for a third the price that will do three times the job.
Eben is right they are more complicated.

Kenny, I think you're reading Eben's post upside down. He loves the Digitry and hates the Partlow.

What I won't do is to get a Digitry that runs multiple units. People love that until it fails and knocks out everything at the same time , or the units fail, one by one. The Partlow on the other hand is a nightmare as far as I'm concerned but I would say the same about watlow units as well. Many of these things have way more bells and whistles than we really need. At least Watlow has a good help line. I recall people last year having trouble with the Digitry and they were unable to get anyone to answer the phone since someone was out of town.

My Love controls don't really fare any better. I've had them for decades and only one has actually failed but the programming is difficult. The worst part is that if you have completed a program and not reset the unit, which is always the case after an overnight annealing job, and then there is the slightest power failure, the program then runs in reverse which is a potentially serious issue. I have had annealers open and left the building while the last portion of cooling goes on, and the power goes out. Then the kiln turns back on and the heat simply rises to go where ever. That can happen on Mary Beth's slumper too and she often leaves flammables on top of the thing. That's a disaster waiting to happen.

So, I think it's a case of pick your poison. If the Digitry works as simply as some say, Mary Beth will really like it on her new box. She just flails when I try to show her how to put a program into the Love 16A. It was about $180.00 in 1980. I have a lot of stuff from back when I ran a large production shop and admittedly have a number of Love and Partlow controllers on hand. They are still a PIA. These days it's such a luxury to have the tooling for a staff of seven when It's just the two of us absentmindingly puttering now.

I did enjoy entering profiles into a Digitry. More user friendly. I most likely won't opt for any controller for multiple units because of the single point failure issue. But they are really nice.

How a unit performs after loss of power is a primary issue for me. The Watlow will default to whatever set point you manually enter before running a profile. I think Fuji does this too, but they're even more clunky than Watlow. You can have your work still nice and toasty at annealing temp the next morning.

If it's your only annealer I guess you'd be screwed for the next day's production, so yes, pros and cons for everything.

These folks were at the GAS conference - looks like a really promising product. I was so excited I forgot to ask the price.

I had a small watlow for the furnace when I started. It was OK... you could set a ramp in degF/hr but no real programming. Then it died (under warranty). Eventually I got a new one but...

Checking the 'net I found the Fuji PXR series was much cheaper than the Watlow I had, and it had programming capability. Realizing that programming the thing was a nightmare from the paper sheet, I invested in the RS485 version and a RS485-to-USB box for my computer. The software was free from Fuji, and made programming (and remote monitoring) the thing a breeze.

I have Fuji's on my annealer and my furnace, and so far they have performed as they should.

Richard,
That sounds like a good controller. The PC connection for programming makes good sense. Trying to set so many modes & variables using the 3 or 4 buttons on these little controllers is nuts.

A simple solution here is to add a start-stop relay. Same premise as you might see on an industrial-grade table saw: one button starts the motor, and another button turns it off. (In the case of an annealer controller, you wouldn't use the "off" button much.) The start-stop box hides a small relay, which maintains the "on" state until power is removed, either by pressing the "stop" button, unplugging the device, or a power outage. If power is returned upstream of the switch, the device will not turn on again until the 'start' button is pressed. In the case of your annealer, if the power goes out your controller will not restart itself without you physically there to re-set it to a meaningful state.

Here's a schematic and some discussion of what's going on (it goes on to discuss more complicated topics unrelated to the task at hand): http://www.electroschematics.com/864...relay-circuit/

I have a backup gb4 just in in case..

Kenny, my digitry will keep my furnace within 2 degrees. My partlow would always be 20 degrees above set point. Always.

Operator error, Eben. You can tune it.

I do not like partlows though

Pete, I got up in the attic and checked yesterday and I think I have enough elements for now, especially since I have no clumsiness planned for the immediate future. (I hope)

What's really funny is that I started inspecting the parameters after programming. As a result I can alter quite a few of the programming parameters from the front panel now without needing the PC to be connected.

In the Calgary studio I had wires buried from the shop to the house electrics and included a 2-wire set so the controller PC was a server in the basement.

Here I never bothered... I just plug in an old laptop when I need to make major changes to the program (like start up vs. charge & run).
