| Abstract: | Based on the detailed analysis of measurement error for the water cooled thermocouple, the design keys of reducing error were presented. The application in the experiment of an aeroengine afterburner sector show that the accuracy of the thermacouple is improved （error within ±1%） under 1820℃. The thermoeouple measurement data can apply directly to the calculation of combustion efficiency. |
