Abstract (en)
Support device for pressure sensors capable of being arranged inside the pressure chambers (7) of centrifugal fans (1), comprising a body (11) with a mainly longitudinal development internally affected by a through-tube (12) extending along the direction of longitudinal development and open at either longitudinal end (12a, 12b), the body comprising a first part (13) for obtaining support from the fan casing and a second part (15), extending from the first part (13), capable of being immersed in the flow generated in the fan's pressure chamber (7), by means of preset positioning of the corresponding end opening of the tube inside the flow, so as to pick up, through the tube (12), a pressure signal, in which the second part (15) of the body (11) has a section that lies across the direction of longitudinal development having an airfoil-profile conformation with a low drag coefficient.
