NovaSensor NPC-410 Series

NovaSensor NPC-410 Series

Medium Pressure Sensors

The NPC-410 Series of solid state pressure sensors are designed to provide a cost effective solution for applications that require long-term stability and high volume. Packaged in a dual in-line configuration, the NPC-410 Series is intended for printed circuit board mounting. Optional pressure port and lead configurations give superior flexibility in low profile applications where pressure connection orientation is critical.The NPC-410 Series is based on NovaSensor’s advanced SenStable® piezoresistive sensing technology. The latest techniques in silicon micromachining have been used to ion implant piezoresistive strain gages into a Wheatstone bridge configuration, which is integrally formed on a micromachined diaphragm. Constant current or constant voltage can be used for sensor excitation. Offset and sensitivity temperature compensation and calibration can be achieved by adding external resistors. Additionally, the NPC-410 series is available in pressure ranges from 0 psi to 5 psi (0 bar to 0.34 bar) through 0 psi to 100 psi (0 bar to 7 bar). Please contact NovaSensor for other pressure ranges.

  1. Ambient temperature = 77°F (25°C), unless otherwise noted. Supply current = 1.5 mA. Gauge and differential pressure devices are tested by applying pressure to the positive differential port (P2) and venting to atmosphere the reference port (P1).
  2. External resistors can be added to reduce temperature errors and calibrate the offset and FSO.
  3. Best fit straight line.
  4. Temperature range 32°F to 140°F (0°C to 60°C), reference to 77°F (25°C).
  5. 3X or 200 psi (13.78 bar) maximum, whichever is less.
  6. Exposed materials are pyrex, ceramic, silicon, epoxy, RTV and stainless steel.
  7. 5 psi (0.34 bar) specifications: Linearity: 0.25 ±%FSO.
  8. Port 1 is limited to 60 PSIG for differential and absolute pressure sensors. Contact factory for 50 PSIA/D and 100 PSIA/D units.
