<p>Disclosed are apparatus and a method for remotely measuring the temperature of a hot gas, for example, in fired furnaces. This is achieved by adjusting the physical temperature of a black body (4) until it equals the radiation temperature of the black body (4) as determined by a pyrometer (5) viewing the black body through the hot gases (3). The radiation temperature is the equal to the line averaged temperature of the gas. </p> |
