I am trying to get some perspective as to what needs to be done, and what my options are before I approach someone with my project. | |

A basic on/off controller will probably overshoot and undershoot too much. At this point, get someone that understands this stuff to do this for you. It sounds like you'll need a real controller, and sensing the temperature won't be easy. About the only good thing is that your temperature is low. This is over your head. | |
| Jul 8, 2015 at 21:53 | comment | added | Ryan | Ok so this would work like most conventional ovens do... I am a little concerned about accuracy, since the delay in heat propagation is on the scale of 10 minutes, and I am using this equipment for with the eventual goal scientific publication. My target temperature is about 80'C, and I don't see any reason why I would need run it above a max of 100'C. Would you recommend RTDs for this purpose? I should also remind you that my disk is rotating (about once per hour) so it may be difficult to implement contact thermometers. | |
