SDP3x Differential Pressure and Mass Flow Sensors (SDP33)


SDP3x Differential Pressure and Mass Flow Sensors (SDP33)

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.

Component SDP33 features :

  • Smallest size (5 mm x 8 mm x 5 mm) currently available, opening up new dimension of integration and applications possibilities
