Abstract
L'invention se rapporte à un bouclier de protection pour un détecteur comprenant un élément par exemple en dioxyde de zirconium permettant de détecter un composant d'un mélange fluide. Selon l'invention, le bouclier forme une chambre 70 qui entoure l'élément 30 de détection et il comprend une trappe particulaire 100 que l'on place dans le courant gazeux à analyser permettant d'intercepter et de dériver une partie du fluide gazeux vers la chambre 70 après élimination des particules contenues dans ce courant dérivé. L'invention s'applique en particulier à l'analyse des gaz d'échappement à la sortie des moteurs à combustion interne.
