NPA Surface-Mount Pressure Sensors


The NovaSensor NPA Series features a high stability SenStable® piezoresistive MEMS chip placed in a SOIC 14-pin miniature thermoplastic package, and is intended for printed circuit board mounting. The sensor monitors pressure in industrial and medical applications by producing a voltage output that is linearly proportional to the input pressure.
