Description
The MS7228 is an absolute silicon micro-machined pressure sensor for harsh environment. A vacuum reference cavity is sealed on top of the sensitive silicon membrane by the anodic bonding of a Pyrex? cap. The pressure, applied on the backside, is converted in electrical signal by piezo-resistors implanted in the silicon membrane. To improve the sensor stability, a drilled Pyrex? is bonded on the backside. As the pressure port consists of Pyrex? and silicon, both stable in most of the chemicals, the MS7228 is suitable for media-resistive applications.
