NPP-301 Series Specications
Description
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.
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.
