Let’s talk about the drift of a Thermocouple.
In this video Dietmar will explain that the drift is not caused by poor quality but mere physics. A Thermocouple consists of two wires and high temperatures can cause diffusion a change in materials. So at the end the alloys produce less thermo-electric voltage thus resulting in a negative deviation of the sensor. This video you will show what you can do about it.
