Title
(EN) SENSOR BODY CELL OF A PRESSURE SENSOR
(FR) CELLULE DE CORPS DE CAPTEUR D'UN CAPTEUR DE PRESSION
Abstract
(EN)
A sensor body cell (144A) for use in a pressure sensor (122) includes a metal housing and an insulating cell (150A). The metal housing (146) has a first cavity (154A) with a first conical inner surface (179). A portion of the first conical inner surface (179) is concave. The insulating cell (150A) includes a first seal portion (170) within the first cavity (154A) and forms a seal with the first conical inner surface (179).
