Help me set up a PID temp controller w/ heating element

Click For Summary
SUMMARY

The discussion centers on setting up a PID temperature controller for heating styrene to its forming temperature of 325°F. The user seeks alternatives to a high-amperage heating gun and explores options such as radiant heating elements and nichrome wire. The conversation highlights the need for a suitable thermocouple, as the provided type K thermocouple is inadequate for the application. Additionally, the user inquires about the necessity of a Solid State Relay (SSR) for effective temperature control.

PREREQUISITES
  • Understanding of PID temperature control systems
  • Familiarity with thermocouples and their applications
  • Knowledge of heating elements, specifically radiant heaters and nichrome wire
  • Experience with Solid State Relays (SSR) for controlling high-power devices
NEXT STEPS
  • Research the specifications and applications of type K thermocouples
  • Learn about the construction and use of nichrome wire heating elements
  • Explore the setup and configuration of PID controllers for temperature regulation
  • Investigate the role and installation of Solid State Relays in heating applications
USEFUL FOR

This discussion is beneficial for hobbyists, DIY enthusiasts, and anyone involved in temperature control systems, particularly those working with materials like styrene and seeking efficient heating solutions.

I need to heat styrene to its forming temp of around 325 degrees F. I have a heating gun that operates at too many amps to use safely at home. So I found these temp controllers that don't use a lot of energy, but can get hotter then my blow dryer can, yet not as hot as the 700 degree heat gun I have. So its a good compromise. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330211540965&ssPageName=ADME:B:WNA:US:1123"
Now this comes with a type K thermocouple which won't work for my application. What do I need to get this all going? Do I need a radiant heating element or will some bent bare nichrome wire inside some old cooking pans with insulation work? Also this will only need to heat 2ft x 2ft. Do I need an SSR or one of these guys too? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270211770451&ssPageName=ADME:B:DBS:US:1123"
This is all really new to me. I'm a total newb. lol Maybe I'm going about this all wrong. ANY help would be greatly appreciated.

THANKS!

325°F. Sounds like a perfect application for your home oven.

But if you want to learn a little about temperature control, you might want to take a look at http://www.omega.com/temperature/Z/zsection.asp" .
