Abstract
Appareil pour la mesure de l'humidité d'un échantillon planiforme comprenant un oscillateur hyperfréquences modulé 1, des atténuateurs 2, 4, 4a, 4b, 9, des coupleurs directionnels 3, 3a, 3b, des cornets émetteurs 5, 5, 5b rayonnant à travers l'échantillon 6 vers des récepteurs 7, 7a, 7b. Les tensions aux bornes des détecteurs 8, 8a, 8b et 10 permettent d'évaluer la teneur en humidité de l'échantillon. Application à la régulation automatique d'appareils d'imprégnation ou de séchage en vue d'une répartition uniforme d'un bain sur un échantillon en bande.
