Abstract
PURPOSE: To reduce the required time of fetch gas to the analyzer for constant time, by switching two sets of gas sampling tubes sequentially to the gas analyzer in a given period and cleaning other sampling tube when one set of gas sampling tube is connected to the analyzer.
CONSTITUTION: Assuming that the probe 13A is connected to the analyzer 14 and the probe 13B is in waiting among two sets of probes, the valves (V) and 8 are opened and the nitrogen gas supplied from the tank 21 is blown transversally to the filter in the probe 13B and then V7 is opened. Then, V8 is closed and blown longitudinally, blowing out dust from the filter. Next, in change-over from the probe 13A to 13B, V9 is opened before it, the gas replacing pump 16 is driven to suction exhaust gas from the probe 13B and to replace the remaining nitrogen gas. Thus, two sets of probes are sequentially changed over to clean the filter of the probe in waiting, allowing to reduce the required time to fetch gas to the analyzer and to keep it constant.
