The invention relates to a method for manufacturing a force sensor and a facility for implementing same. The method includes the following steps: a) providing a deformation measurement apparatus (22) and a proof body (10); b) providing a reactive viscous adhesive; and c) applying said reactive viscous adhesive (14) to said proof body (10); d) placing said deformation measurement apparatus (22) on said viscous apparatus applied such as to trap a layer of said reactive viscous adhesive (50); then applying pressure to said deformation measurement apparatus (22) in order to bring same to a given distance from said proof body (10); and e) causing said reactive viscous adhesive of said layer (50) to react in order to sealingly secure said deformation measurement apparatus (22) to said receiving surface (12) of said proof body (10).
