Packaged in a dual-in-line configuration, the NPC-1220 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-1220 Series is based on NovaSensor’s advanced SenStable® piezoresistive sensing technology. Silicon micromachining techniques are used to ion implant piezoresistive strain gages into a Wheatstone bridge configuration. The NPC-1220 Series offers the added advantage of superior temperature performance over the temperature compensated range of 32°F to 140°F (0°C to 60°C). A current set resistor is included to normalize the FSO for field interchangeability. Additionally, the NPC-1220 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 6.89 bar). Please contact NovaSensor or other pressure ranges. NPC-1220 Series schematic diagram 1. Tube length; L = 0.490, S=0.325, N = No tube. 2. Lead pins can be in either 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.
