LEL-waarde, explosiegrens - Hitma Gas- en vlamdetectie

LEL-waarde, explosiegrens. O2/Dizuurstof/molecaire zuurstof, meer info. . De mengverhouding van gas/damp en zuurstof waarbij een brandbaar mengsel ontstaat, is niet voor elk gas gelijk. De getallen lopen zelfs enorm uiteen. In de vakliteratuur wordt de explosiegrens aangegeven door de afkorting (LEL), van " Lower Explosive Limit ".

LEL-sensoren en correctiefactoren - Safety Detection

Een LEL sensor neemt de som van de brandbare gassen en is NOOIT specifiek! Een uitlezing op jouw LEL-meter is dus nooit exact. Er wordt geen specifieke meting naar 1 bepaald gas gedaan. Een LEL-sensor heeft een verschillende gevoeligheid voor verschillende gassen. Deze gevoeligheid wordt uitgedrukt in een correctiefactor. Hoe minder gevoelig de sensor voor het gas hoe hoger de …

Infrarot UEG-Gassensoren – Risiko oder Chance?

Setzt man den Sensor für die Erkennung brennbarer Gase in einer Umgebung ein, in der eventuell auch H 2 vorhanden ist, wäre der Benutzer völlig ungeschützt. Hersteller von Gaswarngeräten, die Infrarot UEG-Gassensoren mit ihrem geringen Stromverbrauch verwenden, begegnen diesem Argument mit dem Hinweis, dass die Wasserstoff-Querempfindlichkeit des Kohlenmonoxid (CO)-Sensors, der ...
