Silicon micromachining techniques sensors are designed to provide a cost effective are used to ion implant piezoresistive strain gages solution for applications that require calibrated into a Wheatstone bridge configuration. The NPC- performance over a wide temperature range. 1220 Series offers the added advantage of superior Packaged in a dual-in-line configuration, the temperature performance over the temperature NPC-1220 Series is intended for printed circuit compensated range of 32F to 140F (0C to 60C). board mounting. Optional pressure port and lead A current set resistor is included to normalize the configurations give superior flexibility in low profile FSO for field interchangeability. Additionally, the applications where pressure connection orientation NPC-1220 Series is available in pressure ranges is critical. from 0 psi to 5 psi (0 bar to 0.34 bar) through 0 psi to 100 psi (0 bar to 6.89 bar).

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. 3. Gauge and differential pressure devices are calibrated by applying pressure to the positive differential port (P2) and vent- ing to atmosphere the reference port (P1). Absolute pressure devices use only P1 to apply vacuum or pressure.
