Specification of

Thermocouples are pairs of different metal cables which are joined together at one end, which produces a clean thermoelectric voltage between the open pairs according to the temperature difference between the edges. The intersection that is inserted into the process where the temperature is being measured is called HOT JUNCTION. Other intersections that are at the last point of the thermocouple material and which are almost always in some types of measuring instruments are called COLD JUNCTION. Thermocouples are available both as bare wires that offer low cost and fast response times or are built into probes. Various kinds of probes are available, suitable for various measurement applications (industrial, scientific, food temperature, medical research etc.).
