Product Description

Thermocouple wire allows temperature to be measured electronically. A typical thermocouple construction consists of a pair of dissimilar metals that are electrically joined together at the sensing point and connected to a voltage measuring instrument at the other end. When one junction is hotter than the other, a thermal "electromotive" force (in millivolts) is produced that is roughly proportional to the difference in temperature between the hot and cold junctions. 

NiCrSi-NiSiMg(Type N) thermocouple is the latest base metal thermocouple, developed to improve the drawbacks that type K thermocouple has. The main chemical composition of positive leg NiCrSi(NP) is Ni:Cr:Si~84.4:14.2:1.4;negative leg NiSiMg (NN) is Ni:Si:Mg~95.5:4.4:0.1.Type N thermocouple also be used in the similar atmospheres that type K works, and the operating temperature range is -200~1300ºC.Type N thermocouple improves the EMF drift and short term EMF change, compared to type K thermocouple, and has a longer life than type K thermocouple. Therefore, in the industries where temperature control and measurement are especially critical, type N thermocouple has more advantages than other thermocouple as it has long life and stable thermal EMF.
