SDP31-500PA

SDP31-500PA is a small, digital differential pressure sensor 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. It 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 sensor is based on the next generation of the CMOSens® sensor chip and is the heart of Sensirion's new sensor platform for measuring differential pressure and mass flow. The sensor is reflow solderable, provides extended functionality, such as multiple I²C addresses and interrupt functions and a fast sampling time. It features excellent accuracy and long-term stability and has no zero-point drift.
