LeSyphon Said:

thermocouple or RDT I need (still confuse with the difference in therminology)

Posted March 6, 2013 link

Both are sensors.  The RTD is Resistance Temperature Detector.  A resistor with 2 wires to connect it to the PID and the resistance varies with temperature and the PID is set to measure this.  A thermocouple is 2 wires of different metallurgy fused into a bead that gives off a small current and that current changes with temperature.  RTDs have been adapted by Auber and but into usable connectors such as a proper threaded screw or a bimetallic thermostat base.  Many thermocouples have been adapted for industrial use and have industrial insulation and connectors.

If you decide on the Auber RTD then get the Auber PID.  Decide whether you want to chase down your own SSR on ebay and whether you want a box.  I would only buy a box for the 1/32 DIN PID, and then only if you wany it.  Note that many people do not house the PID, it sets on top of the machine unboxed.  Also note that there AC terminals on back that you could potentially grab.  You could tape those over or insulate if you do not box.

If you want to piece it together, then get stuff on Ebay.  Downside is instructions, but they you can probably figure it out.  I have not actually seen one and have seen some instruction on ebay.

I used 3 functions thus the 1/16 PID controller that I chose, and I am not suggesting that for you.  Just a PID controller with SSR and 1 alarm.

About wires...  If you crimp, not solder, then you need to get wire size to crimp; wire should match connectors.  I think that you should use 14 awg for the SSR output but 16 awg may be ok.  I would use 16 awg if that was what used in the machine, if I could read that on the wire, otherwise 14 awg.  If 16 awg then you can potentially use it throughout.  I used 14 awg for SSR output and 26 awg on the rest.  I had it and it is small to put in the bundle to the PID controller.  I have 10 wires in that bundle and you will have 8 if you use steam.  I am assuming that you can use steam and that we can figure the connections.  I do not have your machine, only the PartsGuru diagram.

Wire needs to be insulated for 105C or greater.  Generic wire for speakers and such is not that temperature.  Give it some thought and decide what you want to do.  Look at the supplies needed on that Gaggia thread.  DIY or an Auber Kit.  If you read the Gaggia thread then you have an idea about wires and connectors, you need the similar stuff.

Thanks for the follow up post.  I wondered where you went.  Let me know when you are ready.  

The good news with a PID controller is that you can in general use it over.  Most wiring is similar.  Obviously you could desire an upgrade and not need it, but if you are at SBDU machine(s) for a while, on student budget, you can use it on the next.
