Abstract
L'invention porte sur un agencement (100) de mesure d'une propriété d'un gaz (2) pour un moteur à combustion interne (120), comprenant une sonde (10) de mesure s'étendant suivant un axe (A) de la sonde (10) perpendiculaire, ou sensiblement perpendiculaire, à une direction d'écoulement (G) d'un gaz (2), la sonde (10) comprenant un élément sensible (11) coiffé par une cage interne (15) ajourée, la cage interne (15) étant elle-même coiffée par un capot (20), caractérisé en ce que l'agencement (100) comprend un déflecteur (30 ; 30') associé à la sonde (10) de sorte à former un obstacle au niveau d'au moins un orifice radial (21) disposé à l'arrière du capot (20) par rapport à la direction d'écoulement (G), afin de favoriser le passage d'un débit d'un gaz (2) au contact de l'élément sensible (11) de la sonde (10).
