摘要： The invention relates to a system for measuring pressure, including a pressure sensor comprising: a deformable membrane on which is placed a resistive bridge able to deliver a bridge voltage representative of a deformation of the deformable membrane caused by a pressure applied to said deformable membrane; a system for limiting the deformation of the deformable membrane, able to limit the bridge voltage in the case of an over-pressure or an under-pressure on the deformable membrane; and an amplifying electronic circuit connected to the resistive bridge, able to deliver an output voltage depending on the bridge voltage; the limiting system and the electronic circuit are conjointly configured so that the output voltage makes it possible to distinguish the case of failure of the pressure sensor and/or of the electronic circuit from the case of an over-pressure or under-pressure on the deformable membrane.
