Type N Thermocouple Wire NP (Ni-cr-si) NN (Ni-si-magnesium)



  • Thermocouple Wire

Type N Thermocouple (Nickel-Chromium-silicon / Nickel-Silicon-Magnesium):

The Type N thermocouple is composed of a nickel-14% chromium-1 1/2% silicon (+) wire versus a nickel 4 1/2% silicon-1/10% magnesium (-) wire. The Type N thermocouple is the newest addition to the ISA family. It was developed to be used under the same conditions as a Type K.

Type N should be used in oxidizing or inert atmospheres with a service temperature range between -200°C and 1260°C (-330°F to 2300°F). The addition of silicon and chromium makes this type of thermocouple more resistant to Green-Rot and less drifting when compared to a Type K.

The negative element, or NN, of a Type N thermocouple can be described by any of the following names: Nisil, nickel-silicon, or, HAI-NN1. The positive element, or NP, of a Type N thermocouple can be described by any of the following names: Nicrosil, nickel-chromium-silicon, or HAI-NP1.
