PRESSURE MEASUREMENT DEVICE OF EXCHANGE DUCT COMPOSED OF PLURAL DETECTION HOLES IN THE OUTER SURFACE OF THE EXCHANGE DUCT, A SEALED PRESSURE GATHERING COVER IN THE OUTSIDE OF THE DUCT AND A TUBE CONNECTED THROUGH THE PRESSURE GATHERING COVER

摘要

PURPOSE: A pressure measurement device is provided to improve the reliability of measured pressure information and to simplify the structure of a product by detecting pressure through a pressure sensor after averaging inside a pressure gathering cover. CONSTITUTION: Plural detection holes(2) are formed in the outer surface of a duct(1). A sealed pressure gathering cover(3) is formed in the outside of the duct to store the detection holes. A tube(5) is connected with the pressure gathering cover. The pressure inside the detection holes is detected through a pressure sensor(6) by averaging inside the pressure gathering cover. Thereby, the reliability about the pressure information is improved.
