NovaSensor NPI-19 Series

Medium Pressure Sensors

NovaSensor NPI-19 Series of Medium Pressure Sensors consists of current-driven, media-isolated pressure sensors, incorporating state-of-the-art IsoSensor technology. They are designed to operate in hostile environments while still providing 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.

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.
