A plasma calorimetric probe
A high-temperature calorimetric probe was shown to be a reliable method of measuring temperatures in argon and helium plasma jets in the range 2000 to 10000 K. A number of simple corrections were found to be necessary to account for the heat transfer interactions between the calorimeter, its insulating jacket, and its water-cooled support, as well as for the flow of hcat to the nose section of the calorimeter. At the high temperature level (12000 K), the probe measurements agreed with the spectroscopic data reported in the literature, while the values in the lower temperature range were confirmed by thermocouple measurements. The probe could also be used to measure gas composition and gas velocity, and results of typical applications are given. (auth)
