MOUNTING OF PRESSURE SENSOR

摘要

A capacitive pressure sensor for measurement of the pressure of a fluid comprises a sensor element (1) which is made of a ceramic, in particular glass ceramic, material and in the conventional way has interior capacitor plates. The sensor element (1) is plate-shaped and joined to a surrounding support ring (5''). The support ring (5'') is made of metal and is connected to the sensor elemnt (1) by means of a joint (3') made of ceramics, in particular glass ceramics, at an annular region around an edge line of the sensor element (1). The support ring (5'') can have a shoulder formed by a protrusion (15) in the interior surface thereof, against which shoulder then a region of the sensor element (1) rests and at which the joint (3') is made.
