Description
Français :

Le pénétromètre Penfeld est un appareil de sondage géotechnique. Posé sur le fond, il effectue des mesures à l'aide d'une pointe instrumentée (piézocône) dans le sédiment.

Le pénétromètre est conçu pour travailler jusqu'à une profondeur d'eau maximale de 6 000 mètres.
Il est doté d'une tige poussée dans le sédiment à 2 cm par seconde, jusqu'à une profondeur de 50 mètres.

La tige de 36 mm de diamètre est enroulée sur un tambour de 2,20 mètres de diamètre et redressée plastiquement lors de la pénétration suivant la technique du « coiled tubing ».
