油箱液位绝压数字压力传感器NPI-19A-101A-2

NovaSensor NPI-19 Series | I2C Digital Pressure Sensor

The NovaSensor NPI-19 I2C Digital 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.

NovaSensor NPI-19 I2C数字压力传感器是NovaSensor®NPI系列的成员，采用IsoSensor和I2C接口协议，为OEM用户提供不错的价格和性能。 它们设计用于在恶劣环境中工作，同时提供硅传感器不错的灵敏度，线性度和滞后性。 压阻式传感器芯片安装在充满流体的圆柱形腔体中，并通过不锈钢隔膜和主体与测量介质隔离。 与所有NovaSensor®硅传感器一样，NPI系列采用SenStable®处理，可提不错的输出稳定性。
