摘要:
The invention relates to a method for operating a gas-sampling probe (1), wherein a gas to be analyzed is removed from a process chamber (17) in the region of a front end (1a) of a gas-sampling tube (2) and is conducted in the gas-sampling tube up to a rear end (1b) while being cooled at the same time, in that cooling air (14) is conducted between the gas-sampling tube and at least one outer jacket (3) surrounding the gas-sampling tube, wherein the cooling air is supplied and discharged at the rear end of the gas-sampling tube and the temperature of the gas to be analyzed in the region of the front end of the gas-sampling tube is higher than the temperature of the supplied cooling air, and the gas-sampling tube radiates outwardly, wherein the temperature of the supplied cooling air is higher than the temperature of the discharged cooling air.
摘要:
A separate device comprising a housing (1), which forms an inlet (2) for a material mixture flow, a first outlet (3) for a first partial flow of the material mixture flow and a second outlet (5) for a second partial flow of the material mixture flow is characterised by a radar device (13) which is designed and arranged such that, by means of same, electromagnetic radiation can be transmitted through an interior space (8) delimited by the housing (1) in the direction of the first outlet (3) and is received again as reflected radiation. In this way, a material accumulation can be detected in the first outlet (3) and the separating device can be monitored with respect to an impending blockage.
