Sensirion SDP8xx-Digital & Analog Pressure Sensors
Sensirion SDP8xx-Digital and Analog Pressure Sensors are differential pressure sensors designed for high-volume applications that measure the pressure of air and non-aggressive gases with superb accuracy and no offset drift. The sensors cover a pressure range of up to ±500 Pa (±2 inch H2O / ±5mbar) and deliver outstanding accuracy.
The SDP800 Series digital differential pressure sensors feature a digital 2-wire interface, which makes it easy to connect directly to a microprocessor. The sensors with analog output feature an analog ratiometric voltage output that is configurable to linear or square root by a separate pin.
The sensors' performance is based on Sensirion's patented CMOSens® sensor technology. Sensirion's CMOSens combines the sensor element, signal processing, digital calibration, and analog output on a small CMOS chip. The differential pressure is measured by a thermal sensor element using flow-through technology. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.

COMMERCIAL VENTILATION with VAV
Commercial ventilation with variable air volume controller (VAV) - Building airflow control solutions
Variable air volume (VAV) is the HVAC system that optimizes air conditioning of the indoor space. The VAV system is engineered to ensure air distribution across a building’s entire ventilation network, using an SDP sensor to measure airflow and dynamically adjust dampers for optimal air delivery. VAV enables increased comfort and +30% energy savings compared with traditional constant air volume systems. A highly-accurate and stable differential pressure sensor is key to secure the return on investment with energy efficiency gains.
