Abstract
A sensor for measuring the relative velocity of an oncoming medium includes a tubular and preferably radially symmetrical sensor body having a leading front end, and a wall with an inner surface defining an axial hollow space being open to the outside at the leading front end. The sensor body includes a preferably streamlined sensor head portion associated with the front end, and a remainder of the sensor body forming a sensor shaft. The wall has at least one conduit being radial or having a radial component. The at least one conduit is separated from the axial hollow space and spaced apart from the front end. The at least one conduit is open to the outside from one of the portions. A method of measuring the relative velocity of the medium includes detecting a first measured value representing the sum of the static pressure and the velocity-dependent dynamic pressure of the medium with an axial pitostatic tube discharging at the front end of a sensor body. At least one second measured value enabling splitting up of the sum is detected with at least one radial conduit in the sensor body separate from the pitostatic tube.
