Abstract: The invention relates to a device for measuring the pressure between two rollers tightly placed against one another or the deformation caused by this pressure in their mutual contact area. The invention is for use in the fields of machines and mechanical assemblies comprising rollers pressed against one another, for example, in printing presses or rolling machines. A crushing width can also be measured, for example, for a deformable seal or a line of glue or cement in an assembly process. This device comprises a thin sensor to be inserted between the rollers and whose shape has a return (14) provided in such a manner that, when the sensor is in a measuring position, the mechanical connections (131) connecting the sensor to the maneuvering part are situated in the squeezing area or on the side opposite the maneuvering part with regard to the squeezing area (ZP).
