The NSCDRRN015PDUNV is a piezoresistive silicon Pressure Sensor offering a ratiometric analog output for reading pressure over the specified full scale pressure span and temperature range. These sensors are intended for use with non-corrosive, non-ionic gases, such as air. Port 1 can also be used for non-corrosive, non-ionic liquids on sensors rated above 60mbar. The absolute versions have an internal vacuum reference and an output value proportional to absolute pressure. Differential versions allow measurement of pressure between two pressure ports. Gage versions are referenced to atmospheric pressure and provide an output proportional to pressure variations from atmosphere.
