Patent ID: 8051719

Claim:
A pressure-sensor device that comprises: a pressure-sensitive component having a body defined in which is a blind cavity with a bottom surface and a peripheral surface, said bottom surface belonging to a membrane portion of said body, there being operatively associated to said membrane portion a detection element; and a connection structure having a duct in communication with said cavity, that is to receive a fluid, a pressure of which is to be detected, said structure comprising: a supporting body of the pressure-sensitive component, defining at least one respective passage; and a compressible element that is designed to be in contact with said fluid and is configured for compensating possible variations of volume thereof, the sensor device further having at least one of: at least one prevalent portion of said compressible element is positioned within said cavity; said duct has at least one narrowing of section configured basically as a capillary passage; or a portion of said structure, through which there extends a terminal stretch of said duct, projects in said cavity and occupies a prevalent part thereof, said portion of the structure including said compressible element.
