So far I have read every thermocouple blog post and article I have been able to find regarding the three governing laws of thermocouples. So far I have not been able to find a suffice explanation as to if this configuration will work or not. I have a system which is 100% in accessible. with no way to get a signal in or out other than a tungsten inlet and a tungsten outlet. Due to pressure, heat, and physical constraints I cannot get any other signal in. What I need to know is whether or not this configuration will be able to yield accurate temperature measurements from inside the system and if so what do I need to do to compensate for the unknown junction. I have attached a diagram so that you can see the wiring. Please if you understand thermocouples, I need some help here. I am truly grateful for any and all assistance you can provide. Thank you so much for your assistance.
