  • Patent number: 10060812
    Abstract: A pressure sensor to measure the pressure of a fluid comprises: a metallic membrane to be in contact with the fluid and on which are stacked an electrical insulator and at least one gauge for measuring the deformation of the membrane, the whole forming a sensitive measuring element a cap comprising: a cover comprising a cavity and holes; conductors located in the holes, the sensitive element exhibiting a face opposite the cap and located in a plane P; wherein the sensor comprises: at least one metallic zone, located in a plane parallel to said plane P, for hermetic sealing of the cap on the sensitive measuring element; continuous metallic tracks comprising parts for picking up contact with the conductors and parts for picking up contact with at least the gauge. A method for manufacturing the pressure sensor is also provided.
