Thermocouple
Thermocouple
A Thermocouple (pronounced: /ˈθɜːrməˌkʌpəl/) is a type of temperature sensor that is used to convert thermal energy into electrical energy.
Etymology
The term "Thermocouple" is derived from the Greek words "thermo" meaning heat and "couple" meaning two different types of metal.
Definition
A Thermocouple consists of two different types of metals that are joined together at one end. When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature.
