Abstract

L'invention concerne un système de détection d'encrassement de filtre de gaz pour surveiller les performances et l'état d'un filtre en fonction d'indicateurs d'accumulation de crasse et d'autres particules sur un filtre placé dans un conduit de gaz, dans lequel un système de notification fournit des alertes et des rapports lorsque le volume d'encrassement atteint un seuil prédéterminé.
