Hi Dan,
There are many different combination's of metals / alloys which exhibit potential differences which change with temperature variation, the most common being the Type K which is Nickel-Chrome / Nickel-Aluminum alloys. Fortunately, for me the different types are color coded so at least I know what type it is that I found in my stores. One thing is curious though the Ni-Cr is non-magnetic but the Ni-Al is magnetic .
This explains thermocouples better than I can. http://en.wikipedia.org/wiki/Thermocouple
Best regards,
Tweakie.
