Certain combinations of alloys have become popular as industry standards. Selection of the combination is driven by cost, availability, convenience, melting point, chemical properties, stability, and output. Different types are best suited for different applications. They are usually selected on the basis of the temperature range and sensitivity needed. Thermocouples with low sensitivitie… WebThe copper-constantan thermocouple shown in Figure 5 is a unique example because the copper wire is the same metal as the voltmeter terminals. Let’s use an iron-constantan (Type J) thermocouple instead of the copper-constantan. The iron wire (Figure 6) increases the number of dissimilar metal junctions in the circuit, as
WebConstantan is a copper-nickel alloy used in a variety of thermocouple applications. It is paired with iron, copper and Chromel® to form types J, T and E thermocouples, respectively. Known for its high electrical resistivity and its ability to perform consistently despite changes in temperature, Constantan is also widely used throughout the ...

WebMay 15, 2024 · Type J thermocouples have iron and copper-nickel legs. It has a narrower temperature range than Type K and would have a shorter life span at higher temperatures. Type J has a higher sensitivity than Type K, which it would be most often compared to. Type J is low cost; however, the iron leg is susceptible to oxidation. WebCopper and Iron. Type E: The Type E thermocouple has a Chromel (Nickel-10% Chromium) positive leg and a Constantan (Nickel- 45% Copper) negative leg. Type E has a temperature range of -330 to 1600 F, has the highest EMF Vs temperature values of all the commonly used thermocouples, and can be used at sub-zero temperatures.
