NPI-19A-300A2

NPI-19A-300A2 is a NovaSensor NPI-19 series digital I2C pressure sensor. It is a member of the NovaSensor® NPI series and incorporates state-of-the-art IsoSensor technology with I2C interface protocols, which gives the OEM user the best in price and performance. It is 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. Applications include industrial process control, corrosive fluid and gas measurement, hydraulic systems and valves, tank level measurement, barometric pressure measurement, ship and marine systems, aircraft and avionic systems and medical equipment.
