How is a thermocouple made
WebThermocouples are sensors that measure temperature. Their applications range from industrial manufacturing and experimental settings to the meat thermometer you use at home. They are often used anywhere it is important to be able to reliably monitor or record temperature data. WebThermocouples measure temperature in terms of voltage, however, rather than directly on a temperature scale. In addition, the response of a particular thermocouple depends on the exact formulation of the metals used to construct it, meaning two thermocouples will respond somewhat differently under identical measurement conditions.
