Question

A thermocouple junction is used to measure the temperature of a solid material. The junction is inserted into a small circular hole and is held in place by epoxy. Identify the heat transfer processes associated with the junction. Will the junction sense a temperature less than, equal to, or greater than the solid temperature? How will the thermal conductivity of the epoxy affect the junction temperature?

Answer 1

Answer:

Conduction,

Less temperature

Epoxy for effective heat transfer by conduction

Explanation:

(1) CONDUCTION is the heat transfer process associated with the junction.

(2) The junction will experience a temperature that is LESS than the temperature of the solid

(3) Epoxy has a high conductivity degree, meaning it transfers heat effectively without much resistance to the heat flow. Hence, to answer the question, the epoxy is used to ensure the effective heat transfer from the solid to the junction.
