Thermostat

Hi Guys & Girls,

Does anyone know of a combination software/thermostat system that can be used to control ramp up, hold and ramp down temperatures?

So basically a thermostat than can be connected to a PC and controlled by the software.

I’ve used an oven controlled by microcontrollers specificly for temperature control. I could program up to 10 steps for ramp, hold and cool. I’ll do a search. I need an oven soon, and controlled temperature is easy, and no need for (post)cure reports and monitoring anymore :slight_smile:

I’ve been looking for the exact same thing. I would love to be able to ramped controls from my PC.

No luck yet…

For the controller itself just go to Ebay and search for “PID ramp” or “PID temperature controller” and you’ll find all kinds of cheap Chinese PID controllers. Or go with Omega, etc.

You’ll also need a thermocouple and relay. Suggest solid state.

If you want to monitor (w/alarms) and record by computer there are all simple programs that will record temperatures based off thermocouple readings. Ebay “thermocouple computer”, etc.

You Sir… are an absolute LEGEND! :smiley:

that’s what I searched for.

Edit:
Found one on ebay with programmable ramps. Ideal for prepregs, and speeding up cures on wet resins, etc. Something for may or later :slight_smile:

Might have to learn LabView and make your own offhand system. Should be easy, since it involves one input, and one output, patched through SS relays and NI breakout box.
NO, I don’t know how to do either, but I’ve dealt with…systems…like that.

Shinko JCL-33A Controller, solid state relay,Voltage spike arrester, thermocouple wire and plugs and computer cooling fan all mounted in an electrical box. You can get an option to link the controller to pc too. All up cost me about $500.00 Aus. We have 2 ovens and can simply change the control box from one oven to the other.

Anyone know how to program a PID for ramps?

I have used PIDs for curing, and they are great.

They have a simple user interface, which is a scrolling menu you flick through.

As the years have gone by, the functions and features have increased to quite an array of steps. You will need the user manual to help guide you through the steps and to make sense of the abbreviations of each mode.

With the PID there is a setting for the ramp rate. You can choose any rate you like from 0.1 degree/minute upwards. I’ve used 0.5 and 1.0 without a problem.
Dwells are also able to be programmed too so your entire cycle can run by itself.
