NPC-1220 Specifications

The NPC-1220 Series of solid state pressure sensors

are designed to provide a cost effective solution for

applications that require calibrated performance over

a wide temperature range. 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 orienta-

tion is critical.

The NPC-1220 Series is based on NovaSensor’s ad-

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. Addition-

ally, 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.

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.
