A thermocouple is an element comprised of two different metals which, combined, produce an electromotive force or a voltage proportional to the temperature at which is it found. Depending on the metals of which the thermocouple is comprised the signals generated are different depending on the temperature. When applied to industry, for the measurement of temperature in the most varied processes, different metal pairs are selected with one of them acting as the positive pole and the other as the negative pole. The fem generated is measured in millivolts and microvolts depending on the thermocouple type. The most usual ones are described below.

Thermocouple Positive Negative
Type K Thermocouple Nickel-Chrome Nickel-Aluminium
Type T Thermocouple Copper Copper-Nickel
Type J Thermocouple Iron Copper-Nickel
Type N Thermocouple Nickel-Chrome-Silicon Níquel - Silicio - Magnesio
Type E Thermocouple Nickel-Chrome Copper-Nickel
Type R Thermocouple Platinum - 13% Rhodium Platinum
Type S Thermocouple Platinum - 10% Rhodium Platinum
Type B Thermocouple Platinum - 30% Rhodium Platinum - 6% Rhodium
