A process is used to determine the direction, the static and the dynamic pressure or the speed of a current on the basis of measured values of pressure or of differential pressures with the help of a new sensor having measuring chambers provided with rectangular or slot-shaped openings arranged along an arc of a circle or along the periphery of a circle. Under the influence of the current, dynamic pressure may build up in these chambers, which contain measuring instruments to determine the pressure in the measuring chamber and/or the differential pressure between two measuring chambers or pressure measuring ducts arranged in the back portion of each measuring chamber. These pressure measuring ducts leave the sensor separately or together with other pressure measuring ducts coming from other measuring chambers. The sensor is basically built in the form of a disk, and two perpendicular disks or sector-shaped disks arranged at the top of a body exposed to a current help to cover a wide solid angle. |
