Thermocouple Temperature Probes

Thermocouple temperature probes are bimetallic probes that are used in various temperature-sensing applications. They consist of two wires, each of which is made of a different metallic element or alloy. The wires are joined at one end to form a measuring junction that is exposed to the fluid or medium under measurement. The other end of the wire is terminated at a reference junction. Current flows through a circuit when the two junctions of thermocouple temperature probes are at different temperatures. The voltage resulting from this current flow is then measured to determine the temperature.
