Abstract

Pour résoudre un problème de défaut d'étanchéité dans un boîtier, on prévoit de munir le boîtier d'un circuit électronique de mesure de son humidité spécifique. On montre qu'en comparant cette humidité spécifique courante à une humidité spécifique initiale, et en évaluant relativement l'écart constaté on dispose d'un outil fiable de mesure de la permanence de l'étanchéité.
