Description
The sensor element of the MS7912 consists of a silicon micro-machined membrane with a Pyrex? glass mounted under vacuum. Implanted resistors make use of the piezo-resistive effect. The absolute pressure sensor (MS7912A) carries a sealed vacuum reference cavity underneath the membrane whereas the differential sensor (MS7912D) has a hole in the Pyrex? glass at the backside of the sensor.
