New versions of the world's smallest SDP3x differential pressure sensor

Sensirion, the world's leading manufacturer of high-quality sensors, is expanding its SDP3x series. The extended measurement range and the additional features of the new differential pressure sensor - such as I2C address selection - open up an even broader scope of application possibilities in the medical technology and consumer goods industry.

The new SDP32 and SDP37 differential pressure sensors feature outstanding performance. Both the digital SDP32 and analog SDP37 enable excellent accuracy in the bi-directional flow range of up to 125 Pa. In addition, the SDP32 allows the user to select from up to three I2C addresses with the ADDR pin, rather than communicating with just one address. Address selection was also added to the existing SDP31. Like the previously launched SDP36, the analog SDP37 has a configurable output signal. The output curve (linear or root square) can be selected with one pin and the latency defined with the other pin (low latency signal or best signal-to-noise ratio). Versions of the SDP3x differential pressure sensor with an extended pressure range will be launched later in 2016.

The new SDP3x differential pressure sensor is considerably smaller than other differential pressure sensors - it measures just 5mm x 8mm x 5mm. This opens up countless new integration and application possibilities. The sensor can be integrated into devices which previously lacked sufficient space for any sensor technology. Apart from its minimal size, the SDP3x differential pressure sensor also stands out thanks to its high accuracy, long-term stability, and no zero-point drift. The SDP3x is reflow solderable, is shipped in tape and reel and is thus the best choice for industrial mass production. The new sensor is particularly suitable for the measurement of mass flow in medical technology, especially in medical ventilation or inhalers, in the consumer goods industry or in various appliances.

Visit us at this year's SENSOR+TEST in Nuremberg between May 10 and 12, 2016, booth 316 in hall 1 and learn more about the new differential pressure sensors in the SDP3x series. More information about the world's smallest differential pressure sensor SDP3x is available on our website:
