DESCRIPTION
The sensor element of the MS7801 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 (MS7801A) carries a sealed vacuum reference cavity underneath the membrane whereas the differential sensor (MS7801D) has a hole in the Pyrex glass at the backside of the sensor.
