Recently, I received a number of questions regarding junctions. Most of the questions are related to the effect of twisted vs. parallel junctions on measurement and performance long term. To answer this question, I approached my friend and colleague at CCPI, Trevor Ford.
Below are some of the questions he answered in his reply. I hope they help you on your next project or simply answer some of the basic questions you might have while working with thermocouples.
Trevor, using your vast thermocouple sensing expertise, would you be able to provide some pros and cons of twisted (weld/no weld)/parallel welded exposed junctions?
