Thermocouple RRLW

A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metals joined together at one end. There are many types of thermocouples, type J, K, T, & E are the most common types (Base Metal), and type R, S, and B thermocouples are used in high temperature applications (Nobal Metal).
