AI overview

A thermocouple is a simple device made of two different metals joined together that produces an electrical signal when exposed to different temperatures. It's widely used in temperature measurement because it's inexpensive, durable, and can work in harsh environments where other thermometers might fail.

A thermocouple, also known as a thermoelectrical thermometer, is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature. Thermocouples are widely used as temperature sensors.
