Type N mineral insulated thermocouple cable

Thermocouple cable Type N is a very common thermocouple junction. Type N, NiCrSil-NiSil shares the same accuracy and temperature range as the type K, NiCr-Ni, but type N is more stable. The temperature range of type N, NiCrSil-NiSil thermocouples is -270°C ..+1260°C.

Type N thermocouple wire

The thermocouple wire of Aeropak is from European origin. More about this thermocouple wire can be found here.

NiCrSi-NiSi thermocouples are suitable for use in oxidizing atmospheres, inert gas atmospheres, or dry reduction atmospheres up to 1200°C (ASTM E230: 1260°C). They require protection from sulphurous atmospheres but are known for their accuracy at high temperatures. The source voltage (EMF) and temperature range are nearly identical to Type K, making them ideal for applications requiring longer service life and greater stability. The Type N thermocouple demonstrates better repeatability between 300°C to 500°C compared to Type K.

Type N still offers superior oxidation resistance at elevated temperatures and a longer service life, especially in environments with sulfur presence, in comparison to Type K. These advantages make it particularly useful in the aerospace, nuclear, and semiconductor industries.

Type N thermocouples are furtermore widely used in various industrial applications, including temperature profiling in ovens, furnaces, and kilns, measuring the temperature of gas turbine and engine exhausts, and monitoring temperatures in the production and smelting processes within the steel, iron, and aluminum industries.
