. A thermocouple is a sensor that measures temperature.
. A thermocouple probe consists of thermocouple wire housed inside a metallic tube. The wall of probe tube is stainless steel
. It is an electrical device consisting of two different type of metals.
. When a thermocouple is grounded, both thermocouple wire and sheath are welded together to form one junction at the probe tip
. When the junction of two metals is heated or cooled, a voltage is created that can be correlated back to the temperature.
. Thermocouple calibration: type K, J & PT100
