Is it true that the thinner the K-type thermocouple wire, the higher the sensitivity?

The relationship between K-type thermocouple wire and wire diameter
Is there any relationship between K-type thermocouple wire and wire diameter? Does a thinner wire result in lower temperature?
The problem is that the wire we used was much thicker than the current one, with a temperature display of around 60 and a temperature display of around 13-30. Where is the problem?
answer:
The K-type thermocouple wire is not related to the wire diameter, and there is no situation where the wire is thin and the temperature is low.
In general, the thickness is the same. If it is a long distance, it is necessary to choose a thicker one to prevent wear and ensure more accurate signal transmission
Your problem may be caused by the following reasons
Is the selection of 1K thermocouple wire correct, and is the division number of K-type thermocouple wire J model? Has the environment for measuring K-type thermocouple wires changed?
Does the 2K thermocouple wire correspond to your thermocouple? Will it be affected by not being blocked? Is there a problem with the wiring of the K-type thermocouple? Is it reversed? Generally, if the temperature reading is reversed, it will result in a lower reading
Is there a problem with the temperature digital display?
In short, the thermocouple, K-type thermocouple wire, thermometer, and model should be consistent
