ADP810 Differential Pressure Sensor

The ADP800 sensor family is Aosong’s series of digital differential pressure sensors designed for high-volume applications. The sensors 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 / ±5 bar) and deliver outstanding accuracy, also at the bottom end of the measuring range. The ADP800 Series features a digital 2-wire I2C interface, which makes it easy to connect directly to a microprocessor. The outstanding performance of these sensors is based on Aosong’s patented sensor technology. The differential pressure is
measured by a thermal sensor element using flow-through technology. The well-proven technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.
