Abstract

L'invention concerne un capteur de pression (1) comprenant un corps de prise de pression (2) à l'intérieur duquel est formé un canal (21) et sur lequel est fixé un capot (3), ledit capteur de pression (1) comprenant un logement interne (4) formé d'une part par le corps de prise de pression (2) et d'autre part par le capot (3) et dans lequel est installé une jauge extensométrique (5), le canal (21) du corps de prise de pression (2) débouchant dans ledit logement interne (4), caractérisé en ce que le capot (3) est vissé au corps de prise de pression (2) et en ce que la jauge extensométrique (5) comprend un corps de déformation (51) qui est fixé au corps de prise de pression (2) et au capot (3) par pinçage du contour dudit corps de déformation (51) entre ledit corps de prise de pression (2) et ledit capot (3).The invention relates to a pressure sensor (1) comprising a pressure tapping body (2) inside which a channel (21) is formed and on which a cover (3) is fixed, said pressure sensor (1 ) comprising an internal housing (4) formed on the one hand by the pressure tapping body (2) and on the other hand by the cover (3) and in which is installed a strain gauge (5), the channel (21 ) of the pressure tapping body (2) opening into the said internal housing (4), characterized in that the cover (3) is screwed to the pressure tapping body (2) and in that the strain gauge (5) comprises a deformation body (51) which is fixed to the pressure tapping body (2) and to the cover (3) by clamping the outline of said deformation body (51) between said pressure tapping body (2) and said cover ( 3).
