摘要：A pressure sensor device (1) comprises: - a pressure sensor (9) having a sensorbody (9a) defined in which is a cavity (11) with a bottom surface (1 Ia) belonging to amembrane portion (9') of the body itself, a detection element operatively being

associated to the membrane portion (9'), - a connection structure (2) having a duct (2a, 15,19) in communication with the abovementioned cavity (11), designed to receive a fluid apressure of which is to be detected. The connection structure comprises a body (2) forsupporting the pressure sensor (9), defining at least one respective passage (2a), and onecompressible element (12) designed to be in contact with the fluid and configured tocompensate possible volume variations thereof, the compressible element (12) beingpositioned at least partially within the cavity (11), in such a manner to substantially divideit into two opposite regions. The device (1) is provided with connection passages (12f) formaintaining different regions of the cavity (11) in fluid communication, i.e. equilibrate inpressure.
