Title (EN) AIR FILTRATION MONITORING BASED ON THERMOELECTRIC DEVICES
(FR) SURVEILLANCE DE LA FILTRATION DE L'AIR BASÉE SUR DES DISPOSITIFS THERMOÉLECTRIQUES
Abstract:
(EN) Systems and methods for monitoring the status of air filters are provided. One or more thermoelectric sensors are provided to have an upstream sensing surface positioned adjacent the inlet surface of the air filter, and a downstream sensing surface positioned adjacent the outlet surface of the air filter. Sensing circuitry are connected to the thermoelectric sensors, configured to receive signals from the thermoelectric sensors and process the signals to obtain status information of the air filter.
(FR) L'invention concerne des systèmes et des procédés pour surveiller l'état de filtres à air. Un ou plusieurs capteurs thermoélectriques sont prévus de manière à avoir une surface de détection en amont positionnée adjacente à la surface d'entrée du filtre à air, et une surface de détection en aval positionnée adjacente à la surface de sortie du filtre à air. Un ensemble de circuits de détection est connecté aux capteurs thermoélectriques, conçu pour recevoir des signaux provenant des capteurs thermoélectriques et traiter les signaux pour obtenir des informations d'état du filtre à air.
