摘要：
A pressure-sensor device (1) comprises:
- a pressure-sensitive component (9) having a body, defined in which is a blind cavity, and having a membrane portion (9a), operatively associated to which is a detection element (R); and
- a connection structure (2), which has a duct in communication with the cavity of the pressure-sensitive component (9) and is to receive a fluid, a pressure of which is to be detected.
The connection structure (2) comprises a supporting body (2a) of the pressure-sensitive component (9), which defines a respective passage (2b), and a compressible element (12, 18) that is designed to be in contact with the fluid and is configured for compensating possible variations of volume thereof. The compressible element (12, 18) is positioned at least in part within the cavity (11) of the pressure-sensitive component (9) and/or in a stretch of the passage (2b) of the supporting body (2a) that is close to the cavity (11) of the pressure-sensitive component (9).
