ABSTRACT:
Exhaust pressure in an exhaust system15that evacuates a processing furnace2is determined as absolute pressure by using a differential manometer23,which measures the exhaust pressure as differential pressure, and a barometer, which measures atmospheric pressure as absolute pressure. An opening of a pressure regulating valve25is adjusted based on the absolute exhaust pressure thus determined so that pressure in the processing furnace2is regulated.
