Abstract:
1. Encapsulated electronic pressure sensor ( 1 ), comprising a sensor chip ( 5 ) configured to measure fluid pressure, comprising an encapsulation ( 2 ) and a support ( 4 ) fitted into said encapsulation ( 2 ), wherein: said support ( 4 ) comprises, on an upper side thereof, a recess ( 41 ) for the sensor chip ( 5 ), wherein said recess ( 41 ) also houses a cushion ( 42 ) with a central hole, as well as an electrical connector ( 45 ), projecting downwards from the lower face of the support ( 4 ), wherein the terminals of said electrical connector ( 45 ) are electrically connected to the outlet terminals of the sensor chip ( 5 ); and said encapsulation ( 2 ) comprises a horizontal structural portion ( 21 ), from which a mechanical engagement ( 22 ), a bed ( 23 ) and a connector ( 24 ) project, wherein said bed ( 23 ) has a cylindrical conformation, with a flat top ( 30 ) with a central hole and an octagonal side surface ( 31 ) with alternate round and flat walls, wherein the internal surface delimited by said walls have a similar and/or cooperative geometry with the side surface of the support ( 4 ); the bottom surface of the recess ( 41 ) of the support ( 4 ), the cushion ( 42 ) and the top ( 30 ) of the bed ( 23 ) of the encapsulation defining an open chamber, inside which the sensor chip ( 5 ) is located, wherein said chamber is in fluid communication with a source of the pressure to be measured by the sensor chip ( 5 ) through the light of the connector ( 24 ) and the central hole as included on the top ( 30 ) of the bed ( 23 ).
