Abstract: This paper gives a new compensative method of high gas temperature measurement. When the compensative conditions are satisfied, the real gas temperature is the indicated value of each thermal-couple. The method presented in this paper, compared with other general methods used before, has many advantages. It can overcome the deficiencies in other general methods used before. Through heating, the effect of radiant heat rejection can be effectively compensated for and the real temperature of high temperature flow gas can be measured directly, precisely and quickly. Its construction is often simple. Therefore it might be useful in aeronautical spaceflighl. chemical and power engineering research fields.

Key words: temperature measurement, thermal-couple, high temperature gas flow
