Abstract
A pressure measurement tool secured to a rod arranged across a duct of an engine of an aircraft. A sheath includes two walls which bound a space receiving the rod, the space communicating with the outside by an opening extending over the length of the sheath, the sheath having a bay extending over the length of the sheath and cavities distributed over the sheath. For each cavity, an air inlet including a passage opens at one end into the cavity another end into the duct. A printed circuit board runs along the bay. For each passage, a pressure sensor in the corresponding cavity faces the passage and is on the printed circuit board. A unit is provided for processing and/or recording the data transmitted by the pressure sensors. It is thus easy to install and makes it possible to take a large number of measurements in the secondary duct.
