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
