Smallest differential pressure sensor, claims Sensirion

February 16, 2016 // By Peter Clarke
Sensirion AG (Staefa, Switzerland) has developed what it claims is the world's smallest differential pressure sensor.

The SDP3x digital differential pressure sensor measures 5mm by 8mm by 5mm and is suitable for the measurement of air flows in medical technology or the consumer goods industry. The new sensor is particularly suitable for portable or mobile medical devices in the field of home care medical ventilation, Sensirion said.

The SDP3x is reflow solderable and available in a pick-and-place package on tape and reel for industrial manufacturing. The SDP31 is digital with an I2C interface, and the SDP36 has an analog output signal. Both versions measure a bi-directional flow range of up to 500Pa. In 2016, new products with extended measurement ranges and different features will be added to the SDP3x series. 

The SDP3x differential pressure sensor is manufactured using Sensirion's CMOSens manufacturing allowing the integration of the sensor element and the evaluation circuit into a single CMOS silicon chip.
