22AWG N Type Thermocouple Wire Stranded Wire 19*0.16mm With IEC 60584 Class 1
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 thermocouple wire type N
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. 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.The positive element, or NP, of a Type N thermocouple can be described by any of the following names: Nicrosil, nickel-chromium-
silicon.
