Abstract

Selon un mode de réalisation, l'invention comprend un appareil pour déterminer indirectement le point de rosée (103) de l'air comprimé à une pression de fonctionnement particulaire comprenant un capteur capacitif (508) pour mesurer une humidité relative (104), un élément chauffant (510) pour à la fois chauffer et refroidir une fraction de l'air comprimé, un dispositif de commande pour commander l'élément chauffant (510) sur la base d'une humidité relative mesurée, un capteur de température (509) pour déterminer la température de la fraction, et le dispositif de commande étant en outre configuré pour commander l'élément chauffant (510) de telle sorte que la fraction soit maintenue à une humidité relative constante prédéterminée afin de pouvoir déterminer le point de rosée sur la base de la température de la fraction.
