Sensirion – SDP800: Digital Differential Pressure Sensor



The SDP800 differential pressure 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 ±500Pa (±2 inch H2O/±5mbar) and deliver outstanding accuracy over the entire measuring range. The SDP800 features a digital 2-wire interface, which makes it easy to connect directly to a microprocessor. The outstanding performance of these sensors is based on Sensirion’s patented CMOSens® sensor technology, which combines the sensor element, signal processing and digital calibration on a small CMOS chip. The differential pressure is measured by a thermal sensor element using flow-through technology.
