0.2mm 32AWG Nisil Nicrosil N Type Thermocouple bare / single Wire
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.
