General Information - thermocouple wire
NiCr-NiSi /NiAl (Type K) thermocouple wire finds the widest use in all basemetal thermocouple, at temperature above 500 °C.
Bare thermocouple wire is typically used to construct thermocouple elements. When selecting the gauge, keep in mind that larger diameter conductors will give a longer service life and will have a higher maximum temperature limit. A smaller gauge thermocouple wire will give you a lower maximum temperature limit and shorter service life, but will have a faster temperature response time. These characteristics must be considered when choosing the appropriate bare thermocouple wire for your application.
