NovaSensor NPI-19 Series | Digital Pressure Sensor I2C

NovaSensor NPI-19 I2C Digital Pressure Sensor

The NovaSensor NPI-19 Digital I²C Pressure Sensor 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. 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.
