NPC-410 Series Medium Pressure Sensors Applications Features Industrial automation Solid state reliability Air flow monitors 0.1% accuracy Process control PCB mountable package Medical equipment DIP package Underground cable leak detection Individual device traceability Description Constant current or constant voltage can be used The NPC-410 Series of solid state pressure sensors for sensor excitation. Offset and sensitivity tempera- are designed to provide a cost effective solution for ture compensation and calibration can be achieved applications that require long-term stability and high by adding external resistors. Additionally, the NPC- volume. Packaged in a dual-in-line configuration, 410 series is available in pressure ranges from 0 psi the NPC-410 Series is intended for printed circuit to 5 psi (0 bar to 0.34 bar) through 0 psi to 100 psi board mounting. Optional pressure port and lead (0 bar to 7 bar). Please contact the NovaSensor for configurations give superior flexibility in low profile other pressure ranges. applications where pressure connection orientation is critical. The NPC-410 Series is based on NovaSensors ad- vanced SenStable piezoresistive sensing technol- ogy. 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.

Tube length L = 0.490, S=0.325, N = No tube. 2. Lead pins can be either be in the same or the opposite direction of the pressure tube. Option (1) has the leads in the Up position, the same direction as the tube. Option (3) has the leads in the Down position, the opposite direction of the tube. 3. Gauge and differential pressure devices are tested by applying pressure to the positive differential port (P2) and venting to atmosphere the reference port (P1). Absolute pressure devices use only P1 to apply vacuum or pressure. NPC-410 Series package diagram
