ELECTRONIC PRESSURE SENSOR WITH IMPROVED SEALING SYSTEM

Electronic pressure sensor comprising a body (20) connectable on one side to a fluid source and housing on the opposite side a mechanical support (30) for a ceramic cell (40) with pressure-sensitive element, and an electrical connector element (50) coupled to said pressure-sensitive element (41), wherein said ceramic cell (40) is of square shape and comprises a thin lower plate or membrane (41) constituting said pressure-sensitive element and an upper plate (42) of greater thickness, on said pressure-sensitive membrane (41) being arranged four resistors (R1, R2, R3, R4) of a Wheatstone bridge, with two resistors (R1, R2) arranged centrally and close one to the other and the other two resistors (R3, R4) arranged radially towards the exterior, wherein the line joining the two most distant resistors (R3, R4) is arranged along a diagonal of the square and said ceramic cell (40) is glued to the support (30) in a perimeter zone (70; 70') such as to leave a central area containing said resistors (R1-R4) free from glue of square or elliptical shape.
