Abstract
A device for connecting, by means of a shielded cable, electrodes to a measuring device, located on either side of a wall ( ) separating an enclosure under pressure from the outside environment. The device comprises a rigid protector sleeve ( ) made of an insulating material that tightly runs through the wall and extends to the immediate vicinity of the electrode, into which shielded cable (C) is passed. A tube ( ) made of a conducting material is arranged in rigid sleeve ( ) and in electric contact with the cable shield. A plug ( ) is secured to rigid sleeve ( ), connected to electrode ( ) and electrically linked to core ( ) of the shielded cable inside metal tube ( ). An electric connector ( ) is associated with rigid sleeve ( ) outside wall ( ) for connection of a shielded wire connected to the measuring device. This device can be used in a system measuring the electrical resistivity of a sample in a frequency range that can reach several ten MHz.
