CONTROLE DE FLUX POUR AIR 3G-CBM-03590

       EMPLOI
       -Pour contrôler et régler un flux d'air dans des installations de
        conditionnement, séchage, refroidissement, etc.
       -Pour la commande de brûleurs, pompes, vannes,
        signalisations d'alarme, etc.

       FONCTIONNEMENT ET INSTALLATION
       -Une palette flexible, est poussée par le flux d'air qu'on doit
        contrôler. Le mouvement est transmis à un microinterrupteur
        SPDT.
       -Le contrôle de flux doit être installé sur un tronçon de conduite
        horizontale, loin de coudes, ventilateurs et points où des
        turbulences excessives peuvent se créer.
