Description
The sensor element of the MS7812 consists of a small silicon micro-machined membrane with a Pyrex? glass mounted under vacuum. Implanted resistors make use of the piezo-resistive effect. The absolute pressure sensor MS7812A carries a sealed vacuum reference cavity underneath the membrane whereas the differential sensor MS7812D has a hole in the Pyrex? glass at the backside of the sensor.
