There were questions about this but I can't find the post. I'm lost
in a sea of vortex posts.
The "POSSIBLE SYTEMATIC THERMOMETRY ERRORS" section of:
http://www.mtaonline.net/~hheffner/Rossi6Oct2011Review.pdf
has been updated with new URLs pointing to pictures of the T2 type
probe.
Here is the section as currently written:
POSSIBLE SYTEMATIC THERMOMETRY ERRORS
Regarding the T2 probe, examine the two photos to the right of this
article:
http://www.nyteknik.se/nyheter/energi_miljo/energi/article3284823.ece
The top one shows the E-cat with the T2 thermocouple probe inserted
down through the T fitting located on top. The second photo shows
the E-cat without insulation and the cover removed. The T fitting
can clearly be seen. The top of the cooling fins almost reach the
bottom of the lid when it is on. The long probe may be resting on
the cooling fins when it is in the fitting.
The length of the probe can be seen in the photos here:

Regarding the Tout thermocouple, examine these photos of the hot end
of the heat exchanger:

The central brass fitting is very thick. Given the hose ID is about
1.5 cm, perhaps over a cm thick. It appears from the wire length the
thermocouple was placed not far from it.
The intermediate section looks to be at least 0.75 cm thick
From the location of the tape, and the protruding thermocouple, in:
http://www.redmatica.com/media/Thermo2.jpg
it appears the thermocouple may have been taped to the large steel
nut, possibly extending into the air beyond it.
Note: the steam/water inters the heat exchanger at the same end where
the Tout thermocouple is located.
If we designate Thot to be the temperature of the water/steam
arriving at the steam/hot water entry port, then there is some
composite thermal resistance R1 from the Tout water to the Tout
thermocouple, and a similar thermal resistance R2 to the Thot water/
steam, then the thermocouple will be at a temperature of 24°C + (R2/
(R1+R2)*100°C. To get an 8°C difference all is needed is for r=(R2/(R1
+R2)) to satisfy:
r * (100°C-24°C) = 8°C
r = 8/76 = 0.1
Here are photos that show the thermocouple before removing the tape:
