Webb19 okt. 2024 · A pitot tube contains two holes that each measure pressure from the incoming airflow. The front-facing hole measures stagnation pressure, and the side-facing hole measures static pressure. The difference between these two measurements results in what is called dynamic pressure, which can then be used to calculate airspeed. WebbThe Pitot static tube’s ports are connected to a differential pressure sensor which measures the difference in pressure between the two ports and gives an electrical output proportional to this difference. Typically this will be in a -2 to +2psi (-14 to +14KPa) range.
