General description
The BMD040 analog output, absolute pressure sensor comprises a piezo-resistive pressure sensor element and a circuitry for signal amplification and temperature compensation. Both components are integrated on a single silicon chip. The active surface of the silicon chip is exposed to a reference vacuum that is formed by an evacuated TO-type housing. The medium to be measured is led up by a pressure nozzle to the back side of the diaphragm, which is resistant to most of the measured media.
