WebA thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature. The thermocouple is a device that is used to measure the temperature of a specific point. The thermocouple consists of two dissimilar metals connected together to create two junctions, the ... WebCrucially, a thermocouple is made up of at least two wires of different metals that, when joined together to form a circuit, create two separate electrical junctions. One junction is located where an unknown temperature needs to be measured (the ‘hot’ or measuring junction), and one connected to a body of known and stable temperature (the ...
WebA thermocouple is a sensor used to measure temperature.
