In an operating well of a deposit or underground fluid storage reserve, which operating well includes an outer wall (1) delimiting, with a central operating tubing (2) of the well, an annular space (4) in which is placed a protective -sheath (6) of an electrical link cable (5) between a surface installation and elements arranged in the well, a device for the measurement of physical parameters includes at least one compact, removable, sealed measuring subassembly (8) arranged in a housing (3) in communication with the interior of the central tubing (2) and at least one compact, sealed connecting subassembly (7) integral with the central tubing (2) of the well and arranged at least partially in the annular space (4) in the vicinity of the protective sheath (6) in order to be connected to the electrical link cable (5). The sealed measuring subassembly (8) and the sealed connecting subassembly (7) have plane contact surfaces (95B, 95A) each associated with a half-transformer (9B, 9A) so as to form an inductive coupling between the measuring subassembly (8) and the connecting subassembly (7).
