<p>In a production shaft of a deposit or an underground fluid storage reservoir, which production shaft comprises an outer wall (1) delimiting with a central production column (2) of the shaft an annular space (4) wherein is placed a sheath (6) protecting an electric cable (5) connecting a surface installation and elements arranged in the shaft, a device for measuring physical parameters comprises at least a compact and sealed measuring subassembly (8) arranged in a housing (3) communicating with the inside of the central column (2) and at least a compact and sealed connecting subassembly (7) integrally connected to the shaft central column (2) and arranged at least partly in the annular space (4) in the proximity of the protective sheath (6) to be connected to the connecting electric cable (5). The sealed measuring subassembly (8) and connecting subassembly (7) have planar contact surfaces (95A, 95B) associated each with a half-transformer (9A, 9B) so as to produce an inductive coupling between the measuring subassembly (8) and the connecting subassembly (7).</p> |
