Research of Thermocouple Cannula Material Used in High Temperature

Thermocouple is one of the most common temperature measure sensors in many fields, such as commercial run and scientific research. Performances ofthermocouple canola material have deep impact on performance indices ofthermocouple, such as long-time stability, service life, and so on. Thermocouple cannulae that work in high temperature should be made of advanced material. This paper deals with feature,classification and application of material of thermocouple cannulae in high temperature, and then expounds puzzle and research status of temperature measurement at high-temperature flux and flow powder.
