Thermocouple Bare Wire

 

Standard and Special Limits of error | bare | solid

Bare thermocouple wire is typically used to construct thermocouple elements. When selecting bare thermocouple wire, keep in mind that a larger diameter conductor 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.
