Anybody have a good source for Thermocouples or RTD's? I recently bought a PID that will work with either type sensor. I don't know the difference between the two, so how do I decide which I need?
I found thermocouples at Automation Direct but they run about $30.00 plus shipping. Seems a little expensive for a temp sensor. I could make my own if I knew what parts to buy. Maybe I could save a buck that way. IDK just looking for suggestions.
