The invention claimed is: 1. A pressure measurement device comprising a pressure sensor of a first type and a pressure sensor of a second type different from the first, which sensors are mounted on a common support in order to be subjected to the same pressure to be measured, in which the pressure sensor of the first type is of the capacitive type, the device being characterized in that the pressure sensor of the first type comprises at least one membrane and a first internal channel passing through the common support and leading into a first sealed enclosure defined in part by a first face of the membrane, a second internal channel bringing a fluid to the membrane is in fluid flow connection with the first internal channel and leading into a second sealed enclosure defined in part by a second face of the membrane opposite from its first face. 2. The device according to claim 1 , wherein the pressure sensor of the second type is of the resistive type. 3. The device according to claim 1 , wherein the pressure sensor of the first type and the pressure sensor of the second type have different failure modes. 4. The device according to claim 1 , wherein the pressure sensor of the first type and the pressure sensor of the second type have different accuracy ranges. 5. The device according to claim 1 , including a processor unit mounted on the common support and connected to the pressure sensors. 6. The device according to claim 1 , wherein the pressure sensor of the first type and the pressure sensor of the second type are mounted on respective opposite faces of the common support. 7. The device according to claim 1 , wherein one of the faces of the common support includes at least one portion covered in parylene. 8. The device according to claim 1 , wherein one of the pressure sensors is enclosed under a hermetic cover secured to the common support. 9. The device according to claim 1 , wherein one of the pressure sensors is connected to wireless communication means.
