The pressure control device includes a correction circuit that corrects a pressure signal, which represents the pressure within the target of pressure control that is detected by a pressure sensor, such that the pressure signal approaches a set pressure signal representing the set pressure; a comparison circuit that compares the corrected pressure signal with the set pressure signal; and a valve drive circuit that controls an opening and closing of a flow control valve based on a comparison result from the comparison circuit. The correction circuit is a filter circuit. The frequency characteristic of the filter circuit has a peak at a prescribed frequency, and corrects the pressure signal so as to raise a component of the prescribed frequency of the pressure signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pressure control device","description":"A pressure control device maintains a pressure within a target of pressure control at a set pressure.
