NPA

main-NPA-sensor

 

The NPA is a new family of OEM miniature pressure sensing products offering best in class performance for OEM applications in healthcare, industrial and transportation markets. Packaged in an industry standard surface mount SOIC14 pin package, the NPA Series is available in Gage, Absolute or Differential pressure ranges from 0 to 10" H20 to 0 to 30PSI with either uncalibrated millivolt outputs or in fully calibrated, amplified analog or 14bit digital outputs.

 

The NPA sensor is intended for printed circuit board mounting and delivered in optional tape and reel ready for automated manufacturing and reflow soldering operations.
