摘要
in the measurement of the temperature of a gas in a space by means of a pyrometer (10) provided with a radiation absorbing shield (11, 12, 16, 17, 27), and a temperature sensor, a thermocouple formed in particular by (23) for producing an electrical signal dependent on the tem the gas temperature, is passed through a gas from the gas space (13) input(14) until the thermocouple (23) and a gas outlet (21), and draw the gas from the space, the gas flow is produced by the application of a relatively low pressure at the exit of gas (21) by pressurized air from a discharge nozzle (20) is pr prepared at the level of the reference screen, absorbing the radiation pyrometer.the pressurized air is brought from a source of pressurized air to the outside of the open space and is directed to the nozzle (20) for a pressurized air passage (19).in such a memory, it can continuously measure temperature of gas flame around 900 for a period very long (more than 1000 hours), simply by creating a flow rate through the thermocouple in the range of 30 to 50 m / s of air supply) essurisu00e9 with a speed of the order of 15 to 100 l / min).the components of the screen are made to absorb radiation heat stable materials such as stainless steel, glass, quartz or a ceramic material which is resistant to high temperatures.
