The NovaSensor NPI Series incorporates state-of-the-art IsoSensor technology, which gives the OEM user the best
in price and performance. They are designed to operate in hostile environments and yet give the 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. As with all
NovaSensor silicon sensors, the NPI Series employs SenStable® processing technology, providing excellent
output stability.

The modular design allows for a variety of pressure port modules, which are hermetically welded to the sensor header module. Standard types A, B, H, and J are shown inside.

For compensation of temperature effects, a complete resistor network is supplied on a hybrid ceramic substrate. The IsoSensor design minimizes temperature errors to provide a maximum offset error of 0.75% FSO over the 32°F to 158°F (0°C to 70°C) compensated range.
