  • Caption: The previous photos are the 2008 version of the 2 wire pair thermistor. I have iterated a bit and this is the 2009 model. I redesigned with an eye towards making them more bombproof. I didn't think the silicone was bombproof. Now this is the nearly final step. The gray cable leads are much shorter, more similar to what is done with the direct-burial telephone cable method. Next, the a copper tube is put over the top, heat-shrinked into place and then the pacakge is filled with a thermally conductive epoxy.
