NPA
Low Pressure
The NPA product series is provided in a
miniature size as a cost effective solution
for applications that require calibrated
performance. Packaged in a SOIC14 pin
surface mount, the NPA-Low Pressure Series
is available in Gauge or Differential pressure
ranges with either amplied analog or digital
outputs. The sensor is intended for printed
circuit board mounting and delivered in tape
and reel form to simplify manufacturing
handling.
