NPI-19 Media-Isolated Digital I2C Pressure Sensors

Amphenol Advanced Sensors' NPI-19 sensors are designed for hostile environments while providing a silicon sensor’s sensitivity, linearity, and hysteresis

Image of Amphenol Advanced Sensors' NPI-19 Media-Isolated Digital I2C Pressure SensorsAmphenol Advanced Sensors' NPI-19 digital I2C pressure sensors are a member of the NovaSensor NPI series and incorporate isolated sensor technology with I2C interface protocols for ideal performance and cost. These sensors are designed to operate in hostile environments while 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 body and diaphragm. The NPI product lines offer 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.
