IMPROVED PRESSURE SENSOR COMPRISING A HERMETIC CASING

摘要

The invention relates to a pressure sensor comprising an electronic body housed in an encapsulation mass (22), comprising a test body (2) provided with, on two opposing faces, a reference pressure chamber (14) and a measured pressure (8) communicating with the outside of the encapsulation mass (22), the electronic body and the encapsulation mass defining, between them, a receiving space (28, 30) for gel, said sensor comprising an opening (34) that communicates the receiving space (28, 30) for the gel with the outside (6) of the encapsulation mass (22).
