Sensirion offers its SDP3x digital differential pressure sensor, which measures just 5mm x 8mm x 5mm and opens up countless new integration and application possibilities, including for the measurement of air flows in medical technology or the consumer goods industry.
The sensor is considerably smaller than other sensors in its segment. It can be built into devices which previously lacked sufficient space for any sensory technology at all. Thanks to the small sensor, existing devices can also be made considerably smaller. The device is suitable for portable or mobile medical devices in the field of home care (medical ventilation) or for products in the consumer goods industry.
The sensor measures differential pressure and is ideal for the measurement of mass flow in a bypass configuration. It is reflow solderable and available in a pick-and-place package on tape and reel for industrial manufacturing. It aalso offers fast signal processing and response time and includes various other digital functions such as multiple I2C addresses and interrupts.
The fully calibrated and temperature-compensated differential pressure sensors are available in a variety of versions. 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 500 Pa. It is manufactured with the latest generation of CMOSens chips. It also integrates the sensor element and the evaluation circuit into a single CMOS silicon chip.
