WO2000050881A1 - Method for determining the concentration of hot gases in an oxygen-containing medium - Google Patents

Abstract

The present invention relates to a method for determining the concentration of hot gases in an oxygen-containing medium, wherein said method involves placing a thermocatalytic element in a measuring chamber and supplying electric current pulses to said element. The concentration of hot gases is estimated from the difference between the thermocatalytic element resistance at a moment preceding the beginning of the formation of a heated-gas boundary layer about said element, moment when the supply of electrical current pulses is interrupted, and the resistance at the same moment in the absence of hot gases in the oxygen-containing medium.
