The SDP1000 series differential Pressure Sensor for air cover the following measurement ranges -5 to 125Pa (0.5inch H2O), -20 to 500Pa (2inch H2O) and - 100 to 3500Pa (14inch H2O). The devices are supplied with 5V and provide a 0.25 to 4V output. Although the output of the differential pressure sensor is analog, the internal linearization and temperature compensation is performed digitally. This results in a superior accuracy, outstanding resolution (up to 0.05Pa) and lowest temperature dependence. The SDP1000 is available with a linear or square root extracted output characteristics at the same price. Since fully exchangeable just a few external electronic components around the device make a high quality differential sensor transmitter with e.g. a 0 to 10V output or other interfaces. Its leading performance is based on Sensirion's proprietary CMOSens? sensor technology which combines the sensor element with amplification and A/D conversion on one single silicon chip.
