Product Data Sheet e GE NovaSensor Description Schematic Diagram The NPP Series features silicon pressure sensors in surface mount packages. An ultra-small Silicon Fusion Bonded (SFB), ultra-high stability SenStable® piezoresistive chip from GE NovaSensor® is placed in a plastic package that exploits high volume, leadframe package technology to bring forth a low-cost sensor alternative to the OEM user. NPP-301 Series With constant voltage excitation, the NPP-301 produces a voltage output that is linearly proportional to the input pressure. The user can provide NPP Series products with signal conditioning circuitry to amplify the output signal or to maximize OEM value added. The NPP Series is compatible with most noncorrosive gases and dry air.
