NovaSensor NPI-15 Series

High Pressure Sensors

The NovaSensor NPI-15 Series of current-driven, media-isolated High Pressure Sensors are designed to operate in hostile environments, and yet give the outstanding sensitivity, linearity, and hysteresis of a silicon sensor. They incorporate state-of-the-art IsoSensor technology, which gives the OEM user the best in price and performance. The piezoresistive sensor chip is housed in a fluid-filled cylindrical cavity and isolated from the measured media by a stainless steel diaphragm and body. As with all NovaSensor silicon sensors, the NPI-15 Series employs SenStable® processing technology, providing excellent stability.

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 errors of 0.75% FSO over the 32°F to 158°F (0°C to 70°C) compensated range.
