These sensors are designed to operate in hostile environments while still providing the same outstanding sensitivity, linearity, and hysteresis of a silicon sensor. The piezoresistive sensor chip is housed in a fluid-filled cylindrical cavity and isolated from measured media by a stainless steel diaphragm and body.


The NPI product line offers a modular design that allows for a variety of pressure sensor port modules that are hermetically welded to the sensor header. These sensors monitor pressure in industrial, medical, and transportation
applications by producing a voltage output that is linearly proportional to the input pressure. As with all NovaSensor silicon sensors, the NPI Series employs SenStable® processing technology, providing excellent output stability.
