IEC standard N Type Thermocouple wire NP / NN ( NiCrSi / NiSi ) alloy wires 3.2mm used for high temperature thermocouple sensor
Quick Description
The Type N thermocouple wire 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 wire is the newest addition to the ISA family. It was developed to be used under the same conditions as a Type K. Type N thermocouple wire 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 wire 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 wire can be described by any of the following names: Nicrosil, nickel-chromium-silicon, or HAI-NP1.
Insulation material: PVC, PTFE, FB or as per the customer's requirement.
Our products conform to the standards of IEC584 -1and IEC-2.
