Topic: Thermocouple question with a suggestion (4 msgs / 80 lines)
1) From: Stephen Jones
If you go to the following thread, you will find some good information about
ordering thermocouples that are more useful (made of thin rods rather than
fiberglass insulated wires) for coffee bean temperature measurements than
those that come with the thermometers.  I have a thermometer like the one
that Tom sells and I think what I've ordered should work.  Since Tom doesn't
sell thermocouples separately and I'm not making commercial references, I
don't think this is violating any of the list's tenets.

Hmmm, Stephen,  I don't know if you noticed but on the omega page it says
"Glass Filled Nylon Molded Transition Junction Rated to 220C (425F)"
that doesn't seem to fit the needs of roasting IME.
I've been using bare tipped fibreglass insulated thermocouples for
quite some time with no real problems. They react extremely quickly
and are quite acurate and repeatable enough for roasting.
 'course that depends on what kind of roaster you are using them in. 
the mechanical arrangement can be a challenge.
I favor the Schulman approach on a pumper or poppery where the lead
crosses the roast chamber just below the top of the beans and doubles
back onto itself with a twist in the center  so that the exposed bead
sits right in the bubbling beans. Like a 'P'.
Other roast setups  will have different reqs.

You didn't read enough of the thread.  The supplier referred to has more
thermocouple configurations than you can shake a stick at.  Broken cup
provided the part number for the one that he uses, together with a lot of
pictures showing how he has it set up.  The fiberglass insulated ones that
come with the thermometers work, but require a lot of effort for persons
like myself because they aren't rigid.  The one Broken cup describes, with
part numbers, is rigid but flexible at the same time.

errrrrrr. actually I did,  I read the thread all the way to the end 
and what I was quoting *were* the specs on the p/n that *he* orderd 
and it still says, just as  in  my previous message, ""Glass Filled
Nylon Molded Transition Junction Rated to 220C (425F)"" for all
those p/n's including the one he has a picture as the one he bought.
Good luck on yopur quest.
