NPP-301
Series
Surface Mount
Pressure Sensor
GE NovaSensor
Description
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 technol-
ogy to bring forth a low-cost sensor alternative to
the OEM user.
With constant voltage excitation, the NPP-301
produces a voltage output that is linearly propor-
tional to the input pressure. The user can provide
NPP Series products with signal conditioning cir-
cuitry to amplify the output signal or to maximize
OEM value added. The NPP Series is compatible
with most noncorrosive gases and dry air.
Features
• Low-cost surface mount package: SO-8
• Wide operating temperature range:
–40 to +125°C
• Static accuracy < 0.20% FSO maximum
• Suitable for automated component assembly
• Four element Wheatstone bridge configuration
for circuit design flexibility
• Solid-state reliability
• 100, 200 and 700 kPa absolute pressure
ranges available
Applications
• Automotive Tire Pressure
• Pneumatic Controls
• Pressure Switches and Controllers
• Altimeters and Barometers
• Cable Leak Detection
• Consumer Appliances
• Portable Gages and Manometers
