NPC-410 Series Medium Pressure Sensors Applications Features • • • • • • • • • • Industrial automation Air flow monitors Process control Medical equipment Underground cable leak detection Solid state reliability ±0.1% accuracy PCB mountable package DIP package Individual device traceability Description 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. Amphenol Advanced Sensors 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 NPC410 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 the NovaSensor for other pressure ranges.
