Sensirion has launched the SDP3x, which is the world's smallest differential pressure sensor. It offers superior precision and repeatability, even below 1 Pa. It also provides long-term stability.

The SDP3x air flow sensor is reflow solderable, and provides prolonged functionality, such as smart averaging, interrupts and rapid sampling time of 2 kHz at 16 bit resolution. The novel sensor is an ideal choice for high volume and cost-sensitive applications where size is vital factor.

Key Features
The main features of the SDP3x sensor are listed below:
• Smallest size measuring just 5 x 5 x 8mm, which facilitates new dimension of applications
• Calibrated and temperature compensated
• Measurement range ±500 Pa (±2 in. H2O)
• Digital I2C and analog output versions
• There is no drift and no zero-offset
• Rapid sampling time of 2 kHz at 16 bit resolution
• Reflow solderable, shipped in "tape and reel" for "pick and place"

Applications
The SDP3x can be applied in the following areas:
• Heating, ventilation, air conditioning (HVAC)
• Medical home care applications
• Lifestyle and consumer products
• Portable medical devices
• Filter monitoring
• Appliances
