Title
(EN) GEOPHYSICAL SENSOR MOUNTING WITH IMPROVED GROUND COUPLING
(FR) MONTAGE DE CAPTEUR GÉOPHYSIQUE À COUPLAGE AVEC LA TERRE AMÉLIORÉ
Abstract
(EN) A nodal geophysical sensing system includes a ground contact sleeve defining an interior space and having at least one feature on an exterior thereof for contacting and compressing ground materials adjacent the exterior. A nodal geophysical sensor having a housing engages at least one feature on the interior space so as to enable acoustic energy transmission between the ground contact sleeve and the housing.
(FR) La présente invention concerne un système nodal de détection géophysique comprenant un manchon de contact avec la terre définissant un espace intérieur et ayant au moins une caractéristique sur un extérieur de celui-ci destinée à entrer en contact avec des matériaux de la terre adjacents à l'extérieur et comprimer ceux-ci. Un capteur géophysique nodal comprenant un boîtier vient en prise avec au moins une caractéristique sur l'espace intérieur de manière à permettre une transmission d'énergie acoustique entre le manchon de contact avec la terre et le boîtier.
