NPP-301B
The NPP-301 Series 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-301 Series is compatible with most
non-corrosive gases and dry air.

The NPP-301 Series features silicon pressure sensors in
surface mount packages. An ultra-small Silicon Fusion
Bonded (SFB), ultra-high stability SenStable®
piezoresistive chip from 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.
