Abstract

Le détecteur comprend un boitier constitué par deux enceintes (10, 12) offrant des orifices dans leurs parois pour former un parcours sinueux a l'air pénétrant dans l'enceinte interne (12). Un transducteur à cellule gazeuse (16) connecté à un circuit électrique (18) fournit des signaux indiquant la concentration du gaz. Le détecteur est alimenté à partir d'une alimentation à distance par des fils (22, 26) et offre des signaux de concentration du gaz par un autre fil (2) à une station centrale à distance.
