とを特徴とする圧力制御装置。 A pressure control device includes a pressure comparator that compares a differential pressure signal from a differential pressure transmitter with a preset pressure target value, and controls an actuator with a control signal generated from the pressure comparator, The differential pressure signal is determined by a pressure sampling time setting means that can appropriately set the pressure sampling time, and a dead band setting means that suppresses the output of the pressure comparator until the deviation amount between the differential pressure signal and the set target value exceeds a predetermined value. A pressure control device comprising an A/D converter for controlling the actuator and converting a signal from the actuator into a digital signal, and digitally displaying the operating state of the actuator on a display panel provided on the front surface of the pressure control device. .
