The SDP3x sensor family is Sensirion’s series of small differential pressure sensors designed for high-volume applications where size is a key requirement. It builds on the next generation CMOSens® sensor chip that is at the heart of Sensirion’s new differential pressure and flow sensing platform.

The digital SDP3x sensor features fast measurement speed, excellent accuracy, and long-term stability and has no zero-point drift. Furthermore, it is reflow solderable and provides extended functionality, such as smart averaging, multiple temperature compensation modes, configurable I²C address, and interrupts.

The analog SDP3x sensors offer a calibrated and temperature compensated analog voltage output. The output signal is configurable: different measurement speeds, output curves, and temperature compensations can be selected, even dynamically during operation mode.
