IEC584 Standard Thermocouple Wire 19 Strands 0.16mm NX Extension Wire
Thermocouple Wire (cable) is available in two grades; Thermocouple Grade wire & Extension Grade wire.
Typically, thermocouple grade is used to make the actual thermocouple sensor or sensing point (junction) itself , whereas thermocouple extension wire (cable) is used to connect thermocouple sensors to associated instrumentation systems, usually via an industrial terminal enclosure or thermocouple connector.
Type N thermocouple grade wire has greater emf stability and corrosion resistance than Type K, however the combination develops a lower emf output and cannot, therefore, be directly substituted.
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.
Type N Thermocouple (Nicrosil / Nisil): The Type N shares the same accuracy and temperature limits as the Type K. The type N is slightly more expensive. The type N has better repeatability between 572F to 932F (300C to 500C) compared to the type K.

Characteristics:
The thermocouple wires have excellent performance and are extensively used in the temperature measurement and control in different fields,
such as metallurgy, chemical industry, petroleum industry, machinery-electric industry, energy industry, agriculture and military industry.
Our products conform to the standards of IEC584 -1and IEC-2.
