AIR PRESSURE TRANSDUCER Russian patent published in 2005 - IPC

Abstract RU 2260780 C2

FIELD: measurement technology.

SUBSTANCE: transducer can be used for measuring parameters of flowing of gaseous media or for determining parameters of motion of transportation vehicles relatively air medium. Transducer has to be a body confined by part of spherical surface 1. There are central 2 and peripheral receiving holes 3-6 on the surface of spherical body. Holes 3-6 are intended for determining direction and value of speed of gas flow. There is also cutting plane of perpendicular axis of spherical surface onto which holes 8-11 are disposed for determining Mach number and static pressure. Static pressure and Mach number are determined in spatial flows of gaseous media which moves with pres-sonic, trans-sonic and supersonic speeds. Reduction in disturbances introduced by transducer into gas flow is provided.

EFFECT: improved precision of measurement; reduced disturbances.
