Title:
センサの構造
Document Type and Number:
Japanese Patent JP5557767
Kind Code:
B2
Abstract:
A sensor structure is provided so that a dynamic pressure effect caused by airflow is avoided as much as possible even when a mass airflow measurement device 16 is integrated with a pressure measurement device 3, thereby preventing contaminated substances, water droplets, or the like from arriving at a pressure measurement part. In the sensor structure, the mass airflow measurement device 16 is inserted into a sensor insertion port 4 provided in an intake air tube component including an intake air tube and is fixed to the intake air tube, and a pressure measurement device 3 is mounted in a housing structural component of the mass airflow measurement device 16 for measuring the pressure. The pressure measurement device 3 and the inside of the intake air tube are connected by a pressure intake port 11 provided in the housing structural component. An opening portion of the pressure intake port 11 is provided on a side face of the housing structural component, and the cross-sectional area of the opening portion is larger than the cross-sectional area of the pressure intake port.
