Thanks for clearing that up for me. However, what is a TO-92 Bug?

The intended use for the temp sensors and data logger is for a 200' deep borehole with a 1" geothermal ground loop and with the temperature sensors attached to it down the borehole. I plan on pumping in heated water (from flat plate collectors, thank you AC) through the pipe to test the different depths for the optimal heat sink storage. Im trying to determine at what depths there maybe loss from a water bearing area. Most wells in the area are from 60' to 120' deep. If I can predict the depth at which the water layer would be, I could stay above or below that to place the heat.
