A method for fixing an assembly onto a gas vessel configured to contain a pressurized fluid. The assembly including a housing, an electronic acquisition board secured to the housing, and a strain gauge. The method including fixing the strain gauge to the vessel using a second adhesive means, the strain gauge being fixed to the vessel in such a way to allow deformation along with the vessel under the effect of the pressurized gas contained in the vessel. Electrically connecting the strain gauge and the electronic acquisition board using at least one electric cable thereby allowing the housing to be free to move relative to the strain gauge. Fixing the housing to the vessel using a first adhesive means so as to cover the strain gauge and thereby leaving a volume of air between the housing and the strain gauge and/or between the strain gauge and the electronic acquisition board.
A method for fixing an assembly onto a gas vessel configured to contain a pressurized fluid, the assembly comprising a housing, an electronic acquisition board secured to the housing, and a strain gauge, the method comprising:
A device comprising a gas vessel configured to contain a pressurized fluid and an assembly, the assembly comprising a housing, an electronic acquisition board secured to the housing and a strain gauge, the housing being bonded directly to the external surface of the vessel by way of a first adhesive means, the strain gauge being bonded directly to the external surface of the vessel by means of a second adhesive means comprising an adhesive of methacrylate, epoxy or cyanoacrylate type, or mixtures thereof, the strain gauge being fixed to the vessel thereby allowing deformation with the vessel under the effect of the pressurized gas contained in the vessel, the electronic acquisition board being fixed to the housing, the strain gauge being electrically connected to the electronic acquisition board by at least one electric cable, the electric cable having a length greater than the distance between the electronic board and the strain gauge, the distance being the distance that exists when the housing is bonded to the vessel, a free space being formed between the strain gauge and the housing and/or between the strain gauge and the electronic acquisition board so that neither the electronic acquisition board nor the housing applies force to the strain gauge.
