What is a Thermocouple?
Two dissimilar metals joined at one end
Generates very small voltage that is used to
calculate temperature at the “HOT” junction
Generally used in harsh and extreme
temperature environments
Many standard Thermocouple types: K, J, T,
N, S, E, B and R
“HOT”
Junction
“COLD”
Junction
Measurement of
interest 10s µV/oC
