Tempting. That's another $30....

I understand how a TC works, how does an RTD function? Is it less finicky about different metals in contacts?

RTDs are resistors.

RTDs can also be extended using any thin wire, (18-22 gauge)...without impacting their performance.

If you want cheap and robust, get yourself one of these suckers:
http://www.ebay.com/itm/RTD-PT100-Te...#ht_1673wt_905

(future thread readers, search ebay for "terminal RTD").

$16 and they are Walker Approved™. I just bought one yesterday, dude already marked it as shipped. Can't wait. (Oh, 4"ish probe, 1/2" NPT thread)

I agree, RTD is superior. I have thermocouples. I've experienced exactly what the OP is describing. Had to take apart the 2-prong thermocouple connector and rewire it.
Good to know others have experienced it.

If you decide to go rtd I buy mine through some guys in Hong King that will make them custom. For example I had rtd sensors with metal springs at the sensor and cut with 1/4" not thread and custom wiring length. The actual rtd length was custom too. I don't think they were more than 20 bucks with shipping from HK. Pro-con was the name

I guess I have been lucky but I have never had trouble with thermocouples. I bought 25 ft of k type thermocouple wire on ebay. I cut it to desired length, hooked it up to my pid and twisted the other ends together. I built thermowells and stuck the twisted end into the thermowell. I have never had problems. I bend my wires all the time as I use one pid as a monitoring thermometer and move the thermocouple from the MLT output to my plate chiller output during every brew day.

Hilarious that I just gave pro-con products a shout out. They will custom make what you need and deliver quick.

Why is that hilarious? Did I miss something?
