Lucas NovaSensor(R) NPC-1210 Low Pressure Series DESCRIPTION The NPC-1210 low pressure series of solid state pressure sensors are designed to provide the same cost effective solution as NovaSensor(R)'s other NPC-1210 pressure ranges. Packaged in a dual-in-line configuration, this NPC-1210 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-1210 series is based on Lucas NovaSensor(R)'s advanced SenStable(R) piezoresistive sensing technology. Silicon micromachining techniques are used to ion implant piezoresistive strain gages into a Wheatstone bridge configuration. The NPC-1210 offers the added advantage of superior temperature performance over the temperature compensated range of 0C to +60C. A gain set resistor is included to provide field interchangeability. The low pressure NPC-1210 series is available in pressure ranges from 0 to 10 inches of water to 0 to 1 psi. Please contact the factory for other pressure ranges.
