Abstract
A pressure detection device including a mount whereon a pressure sensor is attached which comprises a membrane which has a surface intended to be subjected to a pressurized fluid and which is so arranged as to elastically deform according to pressure, and means for determining the deformation of the membrane along an axis normal to a mid-plane of the membrane in the rest state. The membrane is supported by a frame connected to the mount by a mechanical decoupling structure in order to isolate the membrane from stress resulting from a differential thermal expansion between the frame and the mount, with the membrane and the frame being made of the same material.
