Abstract

Es wird eine Vorrichtung zur Erzeugung einer definierten relativen Luftfeuchte angegeben. Diese besteht aus einer Sättigerkammer sowie einer mittels mindestens einer Verbindungsleitung damit verbundenen Meßkammer. Die relative Luftfeuchte ist durch die bloße Variation der Drücke in der Sättigerkammer und der Meßkammer einstellbar. In der Meßkammer liegt in einer möglichen Ausführungsform im wesentlichen die gleiche Temperatur wie in der Sättigerkammer vor. In der Verbindungsleitung ist desweiteren eine Ventileinheit angeordnet. Sowohl die Ventileinheit als auch der zwischen Ventileinheit und Sättigerkammer befindliche Bereich der Verbindungsleitung stehen in thermischem Kontakt mit einer Heizeinrichtung.
