I need ten temperature sensors and so far this is the best I found. Its not ideal for sensing the temperature of gas or liquid in a pipe. The first pic is of the sensor soldered to a piece of strip board so I can solder wires to it. The strip board and solder joints will have heat shrink around it. The second picture is the shape of a small piece of thin copper sheet. The long part will be wrapped around the sensor with the sensor occupying the lower tang and heat shrink-ed to keep it there. Then the larger part will be wrapped around the pipe to effectively get the sensor to the pipe temperature. Then all of it will be wrapped with some insulating material.
And the question: I suspect there is a better way of doing this. Any suggestions? I am open to anything including a different sensor.
Reading the replies I realize I should have presented the application. This is a project to monitor our home HVAC system. There will be one Arduino DUE in a box out by the compressor. It will monitor the Freon pressure in and out of the compressor, the temperature at both places and the temperature out of the condensing coils. It will monitor the temperature of the ambient air and of the exhaust air, and the voltage and current for the compressor and fan. There will be another Arduino Due in the air handler monitor all the stuff there, and monitoring the furnace part. Other than startup current and voltage there is little need for fast response. Yes, I am going overboard with all the sensor points, but I will do that and see what I get.
The Arduino DUE was selected because it has 12 analog inputs built in.
