Pressure sensors with digital i2C interface
MODEL NPS19A
SPI/I2C Board Mount Pressure Sensor
Product Overview
The NPS19A pressure sensor with digital I2C interface, transmit the measured value as a calibrated and temperature-compensated signal. The product range covers absolute and relative pressure in the pressure range from vacuum to 600 bar, Depending on variant, the sensors are ideal for measurement of absolute pressure, or relative
pressure in liquids and gases.
